LAMINS -
Lamins are type V intermediate filament that form the major component of the nuclear lamina (FBrf0200518).
Protein Function (UniProtKB)
Lamins are components of the nuclear lamina, a fibrous layer on the nucleoplasmic side of the inner nuclear membrane, which is thought to provide a framework for the nuclear envelope and may also interact with chromatin (PubMed:3126192, PubMed:15035436). May have a role in the localization of the LEM domain proteins Ote, bocks and MAN1 to the nuclear membrane (PubMed:15035436, PubMed:16439308). In spermatocytes, plays a role in maintaining type-A lamin LamC nuclear localization; regulates meiotic cytokinesis by maintaining the structure of the spindle envelope, and by contributing to the formation of the contractile ring and central spindle (PubMed:27402967).
(UniProt, P08928)
Phenotypic Description (Red Book; Lindsley and Zimm 1992)
Lam: Lamin
The structural gene for nuclear lamin. Translated as a prolamin of apparent molecular mass of 76-kd, which is quickly processed to a 74-kd species, presumably by proteolysis. The processed polypeptide is assembled into the nuclear envelope, where it becomes phosphorylated and again attains a mass of 76 kd (Smith, Gruenbaum, Berrios, and Fisher, 1987, J. Cell Biol. 105: 771-90).
Summary (Interactive Fly)

an intermediate filament protein - chromatin associated protein - Lamin binds to scaffold/matrix-associated regions, DNA sequences that are held responsiblefor mediating the interaction between the nuclear matrix and chromatin.

Additional Descriptive Data

The 3.0 kb Lam transcript is expressed at all stages, from embryo to adult. Although the 2.8 kb Lam transcript predominates in late oogenesis and early embryogenesis, the 3.0 kb transcript predominates starting at 2-3 hours of embryogenesis. Both transcripts encode the same polypeptide, and differ in their 3'-untranslated regions.

Additional Descriptive Data

Lam protein is a nuclear envelope polypeptide which remains in an envelope-like structure enclosing the mitotic apparatus throughout mitosis.

(Campbell et al., 2010, Harel et al., 1989)

Full-length Lam is abundant at 8 hours APF, but decreases from 10-12 hours APF, and is at low to absent levels at 14 hours APF. Cleaved Lam is observed starting at 10 hours APF, and is abundant by 14 hours APF.

(Martin and Baehrecke, 2004)

Lam protein is a component of the individualization complex in late spermatogenesis.

(Arama et al., 2003)

Between stages S4 and S6-S7 of oogenesis, Lam protein localizes to the nuclear periphery in all cell types, but after stage S6-S7, nucleoplasmic and cytoplasmic accumulation is also observed. During larval, pupal and adult stages Lam protein localizes to the nucleus of most cells. No Lam protein is detected during stages 6-11 of spermiogenesis.

(Ashery-Padan et al., 1997, Riemer et al., 1995)

Lam protein is nuclear. There is some, but not complete, overlap in subcellular Lam and LamC protein expression.

    Lam is required in the cyst stem cell lineage but is dispensible in both the germline and the hub cells in the testis.

    (Chen et al., 2013)

    Lam is required to regulate organisation of the stem cell niche in the testis so that both the cyst stem cells and germline stem cells can assume proper interactions with the hub.

    (Chen et al., 2013)

    DNA-protein interactions: genome-wide binding profile assayed for Lam protein in Kc167 cells; see Chromatin_types_NKI collection report. Individual protein-binding experiments listed under "Samples" at GEO_GSE22069 (http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE22069).

    (Filion et al., 2010)

    RNAi generated by PCR using primers directed to this gene causes a cell growth and viability phenotype when assayed in Kc167 and S2R+ cells.

    (Boutros et al., 2004)

    Lam is required for nuclear attachment to the microtubule organizing centre and for localization of klar to the nuclear envelope.

    (Patterson et al., 2004)

    Mutations in Lam disrupt the directed outgrowth of the cytoplasmic extensions from terminal cells of the tracheal system. Female germline mutant clones disrupt the dorsal-ventral polarity of the oocyte.

    (Guillemin et al., 2001)

    Lam protein interacts with both Ote and fs(1)Ya in a yeast two-hybrid system.

    (Goldberg et al., 1998)

    Identification: Enhancer trap expression pattern survey for loci expressed in the ring gland.

    (Harvie et al., 1998)

    Biochemical techniques reveal that in living cells lamins are closely associated with both DNA and RNA.

    (Rzepecki et al., 1998)

    The Lam gene product is essential for the structural integrity of the nuclear envelope and for the correct integration of nuclear pore complexes into the nuclear membrane.

    (Lenz-Bohme et al., 1997)

    Recruitment of fs(1)Ya and Lam to the male pronucleus occurs prior to or during the early stages of pronuclear migration and this accompanies or requires reorganisation of the sperm nucleus.

    (Liu et al., 1997)

    Region of a DNA fragment, λ20p1.4, which is a moderately repetitive sequence of the genome present in about 120 copies per haploid genome, polymerises with purified Lam.

    (Bogachev et al., 1996)

    The alpha-helical rod domain of Lam is sufficient for the specific interaction with the M/SAR fragment of ftz. For this specific interaction to occur it is essential that Lam is organised above the level of the dimer.

    (Zhao et al., 1996)

    Identified as being specifically expressed in the terminal cells of the developing tracheal system and required for the formation and outgrowth of the terminal branches.

    (Guillemin and Krasnow, 1995)

    Monoclonal antibody ADL84 is specific for Lam Dm1 and does not bind Lam Dm2. The antibody demonstrates that isolated interphase Lams Dm1 and Dm2 occur as mixed dimers, indicating random interactions. Mapping of the epitope for ADL84 shows Lam Dm2-specific phosphorylation takes place in the amino terminal head domain, most likely at Ser25.

    (Stuurman et al., 1995)

    Nuclear assembly has been followed in a cell free system: the Lam gene product plays essential role in nuclear envelope assembly.

    (Ulitzur et al., 1992)

    Three isoforms of Lam protein have been purified and their activity in vitro has been studied.

    (Lin and Fisher, 1990)

    Lam has been cloned and sequenced.

    (Osman et al., 1990)

    Some Lam protein is apparently retained in an envelope-like structure throughout mitosis in early Drosophila embryos.

    (Harel et al., 1989)

    A soluble isoform of Lam protein has been identified in the extracts of cultured cells blocked in mitosis. This isoform is the only species detectable in late-stage egg chambers and early embryos. The conversion of nuclear isoforms of Lam protein to this soluble isoform is mediated by a specific rearrangement of phosphate groups rather than large net changes in the levels of Lam protein phosphorylation. The residues involved in the phosphorylation/dephosphorylation reactions have been tentatively mapped within the fragment containing amino acids 385-547.

    (Smith and Fisher, 1989)

    l(2)25Ec was included as part of a study of the 24D4--25F2 region.

    (Szidonya and Reuter, 1988)

    Gene identified by screening a lambda-gt11 cDNA expression library, constructed from early embryonic mRNA, with monoclonal antibodies against Drosophila lamin. The structural gene for nuclear lamin. Translated as a prolamin of apparent molecular mass of 76kD, which is quickly processed to a 74kD species, presumably by proteolysis. The processed polypeptide is assembled into the nuclear envelope, where it becomes phosphorylated and again attains a mass of 76kD (Smith, Gruenbaum, Berrios, and Fisher, 1987).

    Origin and Etymology
    Discoverer
    Etymology

    The gene is named "misguided" because terminal branches of the tracheal system do not follow the normal patterns of projection during branch outgrowth in mutants.
