Protein
Adenomatous polyposis coli protein-related protein 1
Gene
apr-1, K04G2.8
Organism
Caenorhabditis elegans
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Has a role in endoderm cell specification and pharyngeal development. Required for the migration of epithelial cells, organization of the anterior seam cells and ceh-13 expression during embryo morphogenesis. During larval development, apr-1 is required for expression of lin-39 in P3-8.p. Shown to negatively regulate Wnt signaling in vulval precursor cells. Has a role in cell division by establishing the polarity of the mother cell which forms the asymmetries of the daughter nuclei. Thought to regulate export of wrm-1 from the nucleus possibly as part of a complex involving pry-1.6 Publications
