May interact (via CBD/FH3 domain) with Rho1.
The DAD domain regulates activation via by an autoinhibitory interaction with the GBD/FH3 domain. This autoinhibition is released upon competitive binding of an activated GTPase. The release of DAD allows the FH2 domain to then nucleate and elongate nonbranched actin filaments (By similarity). DAD-mediated autoinhibition negatively regulates dia localization to the apical cell cortex (PubMed:23853710).
The N terminal basic region is enriched in basic amino acids that may mediate interaction with negatively charged phosphatidylinositol 4,5-bisphosphate (PtdIns[4,5]P(2)). It is required, but not sufficient on its own, for efficient apical localization in polarized epithelial cells.
The GTPase binding domain (GBD) probably mediates interaction with Rho1 required for disruption of autoinhibition and targeted recruitment to the apical membrane of polarised epithelial cells.

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).
dia transcript is expressed predominantly in tubular organs, including trachea, salivary glands, Malpighian tubules, the hindgut and the proventriculus, starting at embryonic stage 14. Transcript is localized to the apical side, facing the tube lumen.
dia transcripts are expressed in both males and females and are not germline specific.
dia protein localizes mainly to the M lines in the indirect flight muscle sarcomere 1 day after eclosion and then sifts to the Z disc as the sarcomers stop growing.
dia protein is apically localized in tubular organs.
dia protein is found pre- and postsynaptically at the third instar larval neuromuscular junction.

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.
dia is required for generation of apical F-actin in diverse types of epithelial tubes in the embryo.
dia is required for furrow canal formation during cellularisation.
