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

Interacts (via SH2 and SH3 domains) with Dscam1 (via cytoplasmic domain); the interaction is direct and requires Dscam1 to be phosphorylated (PubMed:10892653). Interacts (via SH2 and SH3 domains) with InR/Insulin-like receptor (via C-terminal cytoplasmic region); the interaction requires InR kinase activity, probably for autophosphorylation stimulated by insulin signaling (PubMed:12702880). Interacts with Ptp61F (via C-terminus); this interaction is independent of insulin stimulation (PubMed:21707536, PubMed:8663600). Interacts (via SH3 domain 2) with Pak (via N-terminal PXXP motif) (PubMed:10399914).
Phosphorylated by Src42A and possibly by other tyrosine kinases (PubMed:12014990). Constitutively dephosphorylated by its binding partner Ptp61F (PubMed:12014990).
Possesses 3 SH3 domains, which bind polyproline motifs, and 1 SH2 domain that binds phosphotyrosine (PubMed:8646773). The SH2 and SH3 domains are cooperatively involved in the binding of the cytoplasmic domains of Dscam1 and InR (PubMed:10892653, PubMed:12702880). SH3 domain 1 preferentially binds Dscam1 PXXP motif 1 (PubMed:10892653). SH3 domain 2 preferentially binds Dscam1 polyproline tract (PubMed:10892653). SH3 domain 3 preferentially binds Dscam1 PXXP motif 2 (PubMed:10892653). Interaction of the SH2 domain with Dscam1 requires Dscam1 to be phosphorylated (PubMed:10892653). InR can interact with either the SH3 domains (all 3 domains required) or the SH2 domain (PubMed:12702880). Only SH3 domain 2 binding activity is essential, but not sufficient, for R cell projection targeting (PubMed:9482841). SH3 domain 1, SH3 domain 2 and the SH2 binding activities contribute to R cell targeting but have redundant functions (PubMed:9482841). SH3 domain 2 and the SH2 domain are both essential for targeting and patterning of inner optic ganglion neurons (PubMed:9482841). SH3 domain 2 is necessary and sufficient for binding to Pak (PubMed:10399914).

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).
Comment: maternally deposited
dock transcripts are detected at high levels in embryonic, pupal and adult stages.
dock protein is expressed in receptor cells and localizes to receptor cell growth cones. It is also observed in the lamina and medulla neuropil.

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.

dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.
dsRNA made from templates generated with primers directed against this gene is tested in an RNAi screen for effects on actin-based lamella formation.
Loss of zygotic dock function causes a selective delay in synapse formation by the RP3 motoneuron at the cleft between muscles 7 and 6. In late stage 16 mutant embryos these muscles often lack innervation. By the third larval instar muscles have become innervated by RP3. dock mutants also show subtle defects in the CNS longitudinal axon pathway.
Isolated in a yeast two-hybrid system, by screening for Ptp61F-interacting proteins.

The gene is named "dreadlocks" for the appearance of the receptor cell projection pattern in the mutant.
