aipl-1 encodes a conserved WD-repeat protein that cooperates with ADF/cofilin and is highly homologous to AIP-1; the sequence of the encoded protein is 66% identical to UNC-78; aipl-1 and unc-78 have redundant and overlapping functions in organized assembly of actin filaments in embryonic muscle and the unc-78 and aipl-1 double mutant is embryonic lethal; both AIPL-1 isoforms preferentially cooperate with UNC-60B, a muscle-specific ADF/cofilin for actin filament disassembly in embryonic muscle; AIPL-1 affects localization of only F-actin-bound UNC-60B; AIPL-1 is expressed in the embryonic neurons, the intestine and the body wall muscle, in adult spermatheca and body wall muscles; AIPL-1 majorly functions in early embryonic muscle and can compensate for the function of UNC-78 in the body wall muscle.
Predicted to enable actin filament binding activity. Involved in actin filament organization and regulation of protein localization. Predicted to be located in cortical actin cytoskeleton. Expressed in body wall musculature; head neurons; intestine; and spermatheca. Is an ortholog of human WDR1 (WD repeat domain 1).
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.
