Src64, Src, Src1, Dsrc64B, Dsrc
Src homolog: a protein tyrosine kinase with SH3 and SH2 domains - plays a role in ring canal morphogenesis during oogenesis and the male germline, microfilament ring constriction during cellularization, and modulation of growth and apoptosis. Some of its roles overlap with those of Src42A.

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

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).

Please Note FlyBase no longer curates genomic clone accessions so this list may not be complete
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 JBrowse for alignment of the cDNAs and ESTs to the gene model.
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.
polyclonal
Src64B expression induces JNK-mediated apoptosis or tissue overgrowth when apoptosis is blocked with p35.
Duplicate transcripts identified and eliminated during the migration of annotations from the release 5 genome assembly to the release 6 assembly.
Based on the frequency of observed ovarian defects, the following Src64B alleles can be ranked from strongest to weakest as follows: Src64BΔ17 > Src64BPI > Src64BΔ19 > Src64BKG00213.
When dsRNA constructs are made and transiently transfected into S2 cells in RNAi experiments, an increase in the proportion of G2/M phase cells, a whole range of mitotic abnormalities, spindle abnormalities and chromosome abnormalities are seen.
Src64B plays a role in the cytoskeletal dynamics that occur during cellularization of the blastoderm.
dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.
Src64B is essential for the proper organization of actin in ovarian ring canals.
Src64B is required for the proper growth and stability of ovarian ring canals.
Phylogenetic analysis of the PTK family.
Phosphorylation of the C-terminal tail of the Src64B protein can repress the activity of the adjacent catalytic domain of the protein.
Considered to be the Drosophila sequence homologous to mammalian c-src, based both on its origin and amino acid sequence as inferred from its nucleotide sequence.
Src64B inferred to be a maternally acting gene whose product is required for early embryogenesis.
