See sections below for more information
The gene Imitation SWI is referred to in FlyBase by the symbol Dmel\Iswi (CG8625, FBgn0011604). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: protein binding; transcription factor binding; nucleosome-dependent ATPase activity; DNA-dependent ATPase activity. There is experimental evidence for 14 unique biological process terms, many of which group under: cellular component organization or biogenesis; biological regulation; chromatin organization; organelle organization; regulation of cellular macromolecule biosynthetic process; cellular macromolecular complex subunit organization; anatomical structure development; cellular macromolecule metabolic process; gene expression; regulation of metabolic process. 18 alleles are reported. The phenotypes of these alleles are annotated with: eye; wing disc; mechanosensory chaeta; polytene chromosome; dorsocentral bristle; euchromatin; mesothoracic tergum; condensed chromosome. It has 3 annotated transcripts and 3 annotated polypeptides. Protein features are: ATPase, nucleosome remodelling ISWI, HAND domain; DEAD-like helicase; Helicase, C-terminal; Homeodomain-like; SANT domain, DNA binding; SANT, eukarya; SLIDE; SNF2-related. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of moderate expression. Peak expression observed within 00-12 hour embryonic stages. Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: larval central nervous system. Expression at moderate levels in the following post-embryonic organs or tissues: adult eye, adult central nervous system, larval hindgut, larval Malpighian tubules, larval fat body, larval/adult salivary gland, larval trachea, adult ovary, adult testis, larval carcass. Comments on Affy2 ProbeSet: ProbeSet 1641309_s_at completely aligns to an exonic region common to each of the 3 FlyBase-annotated transcript isoforms of Iswi. Gene sequence location is 2R:8524123..8528133.

Additional Descriptive Data
The pattern of Iswi and brm transcript expression are very similar. Iswi transcript levels are highest in oocytes and early embryos, and lower in late embryos and larvae. Iswi is barely detected in pupae and adult females, but is not detected in adult males. In embryos, both Iswi and brm transcripts are uniformly distributed until germ band retraction. Both gradually become restricted to the central nervous system and are undetectable near hatching. Unlike brm, Iswi transcripts are also detected in gonads after germ band retraction.

Additional Descriptive Data
Iswi protein is detected in all nuclei of embryos, as well as in diploid and polyploid nuclei of third instar larvae.
Iswi protein is detected in all developmental stages. It is at highest levels in mid-embryogenesis, with lower levels in larvae, pupae, and adults. Expression in adult males is ~50-fold lower than in 0-12 hr embryos. Expression in the developing embryo can be as high as 100,000 molecules of Iswi protein per cell.

dsRNA has been made from templates generated with primers directed against this gene. RNAi of Iswi results in increased arborization of ddaD and ddaE neurons, defects in muscle, defects in dendrite morphogenesis and reproducible defects in da dendrite development.
Unilateral binding of Iswi protein to a model nucleosome correlates with directional movement of the nucleosome toward the enzyme.
The NURF complex (composed of Caf1, E(bx), Iswi and Nurf-38 proteins) can remodel chromatin and stimulate transcription in vitro irrespective of the acetylation status of histones.
The Iswi protein per se, out of the context of a multi subunit complex, is able to remodel nucleosomes, rearrange nucleosomal positions and function as a chromatin assembly factor.
ACF (ATP-utilizing chromatin assembly and remodeling factor) is a multisubunit factor consisting of 3 polypeptides. These are encoded by Iswi and by Acf1 (this encodes both 170 and 185kD subunits). The p47 polypeptide seen previously in ACF fractions (FBrf0095281) has been found to be identical to Yp2 and appears to have been a contaminant in these earlier ACF fractions.
The Acf1 and Iswi subunits of ACF (ATP-utilizing chromatin assembly and remodeling factor) function synergistically in the assembly of chromatin.
Trl- and Iswi-mediated disruption of the chromatin structure within the promoter region of ftz activates transcription on the chromatin template.
The ATPase activity of Iswi is completely inhibited by each of the four histone tails (His2A, His2B, His3 and His4), results indicate a novel role for the flexible histone tails in chromatin remodeling by Iswi.
The interaction between Iswi and nucleosomes is impaired by proteolytic removal of the N-terminal histone tails and by chemical crosslinking of nucleosomal histones.
Acf1, a multisubunit factor consisting of polypeptides with molecular masses of 47, 140, 170 and 185kD, has been purified and characterised. The 140kD component is encoded by Iswi.
Once nucleosome remodelling by the DNA binding factor is accomplished a high level of NURF activity is not continuously required for recruitment of the general transcription machinery and transcription initiation. NURF is able to assist gene activation in a chromatin context: remodel nucleosomes for gene activation in chromatin.
NURF, a protein complex of four subunits Caf1, Nurf-38, E(bx) and Iswi, is able to facilitate transcription mediated by a Scer\GAL4 derivative carrying a constitutively activating region from Hsf.
A chromatin-accessibility complex (CHRAC), which uses energy to increase the general accessibility of DNA in chromatin, has been identified. CHRAC can also function during chromatin assembly, using ATP to convert irregular chromatin into a regular array of nucleosomes with even spacing.
The chromatin-accessibility complex (CHRAC) contains 5 subunits, two of which have been identified as the Iswi and Top2 gene products.
Iswi encodes the 140kD subunit of Nucleosome remodeling factor.
Nucleosome remodelling factor is composed of at least four polypeptides that act in concert with the Trl transcription factor at the Hsp70 promoter. Nucleosome remodelling factor acts directly on the nucleosome to perturb its structure.
Identified on the basis of similarity to Scer\snf2.
