eps-8 is encodes a cell signaling adaptor protein that contains and N-terminal PTB domain, and C-terminal SH3 and actin-binding domains; EPS-8 is essential for epidermal and intestinal cells morphogenesis; eps-8 is also involved in trafficking of the LET-23 EGF receptor during vulval development; EPS-8 physically interacts with the ankyrin repeat protein VAB-19 and demonstrates a novel actin barbed-end-capping activity; EPS-8 is expressed throughout development and localizes to sites of cell-matrix attachment and to the apical side of polarized cells.
Enables actin filament binding activity. Involved in several processes, including anatomical structure morphogenesis; barbed-end actin filament capping; and supramolecular fiber organization. Located in apical part of cell; brush border; and hemidesmosome. Expressed in several structures, including P3.pa; P3.pp; P5.ppp; P7.paa; and P9.p. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 102; autosomal recessive nonsyndromic deafness 106; and hypotrichosis 5. Is an ortholog of human EPS8L1 (EPS8 signaling adaptor L1).
gei-19 has been merged into the eps-8 gene following advice from the CGC [krb 030902]
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
