Gene Group (FlyBase)
SPLICEOSOME COMPLEX B -
Nuclear pre-mRNA splicing is catalyzed by the spliceosome which assembles in a step-wise manner. After the assembly of complex A on pre-mRNA, the U4-U6 and U5 snRNPs are recruited as a preassembled tri-snRNP to form complex B. U5 snRNP binds exons at the 5' site. (Adapted from PMID:24452469 and PMID:23118483).
SPLICEOSOME COMPLEX C -
Nuclear pre-mRNA splicing is catalyzed by the spliceosome which assembles in a step-wise manner. Complex B undergoes a number of structural rearrangements and U4 and U1 snRNPs dissociate to generate complex C, the catalytic spliceosome. (Adapted from PMID:24452469 and PMID:23118483).
SPLICEOSOME COMPLEX P -
Nuclear pre-mRNA splicing is catalyzed by the spliceosome which assembles in a step-wise manner. Complex P, the post-spliceosomal complex, is formed after the catalytic removal of the intron by complex C. Complex P contains the lariat intron and spliced exons. (Adapted from PMID:24452469 and PMID:23118483).
Protein Function (UniProtKB)
May be involved in pre-mRNA splicing process (PubMed:12163015, PubMed:2044955). Involved in embryonic neurogenesis and cell rearrangement during Malpighian tubule morphogenesis (PubMed:2044955, PubMed:10502111).
(UniProt, P17886)
Phenotypic Description (Red Book; Lindsley and Zimm 1992)
crn: crooked neck
Hemizygous embryos from heterozygous mothers show twisted phenotype; crn3/Df(1)64c18 and crn4/Df(1)64c18 exhibit a similar but more extreme phenotype, suggesting that they are hypomorphic. Both alleles lethal in female germ-line clones.
yok: yolky
Mutants are embryonic lethals with an undispersed yolk plug and no visible Malpighian tubules. Cuticle phenotype normal.

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

        Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see GBrowse for alignment of the cDNAs and ESTs to the gene model.

        Drosophila Genomics Resource Center cDNA clones

        For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.

        Identified as a potential component of the hh signalling pathway in a genome-wide RNAi screen. dsRNA made from templates generated with primers directed affects the extent of expression of a hh signaling reporter construct in Clone 8 cells.

        Muscle phenotype of mutants studied using polarised light microscopy and antibody staining to detect Mhc-lacZ reporter gene expression in muscles.

        (Drysdale et al., 1993)

        Molecular analysis of crn indicates it is related to a family of genes required for normal progression through the cell cycle. Sequence similarity and mutant phenotype suggest crn encodes a protein required for cell division. Zygotic expression of crn is required to complete late rounds of cell division in the embryonic nervous system.

        A screen for X-linked genes that affect embryo morphology revealed yok.

        A saturation analysis of the 2D3--2F5 region detected the crn complementation group.

        Germline clonal analysis indicates that this locus is required for female germ line viability.

        (Perrimon et al., 1984)

        crn3/Df(1)64c18 and crn4/Df(1)64c18 exhibit a similar but more extreme phenotype, suggesting that they are hypomorphic. Both alleles lethal in female germ-line clones
