hmp-1 encodes an alpha-catenin; during development, hmp-1 activity is required for proper enclosure and elongation of the embryo; HMP-1 localizes to hypodermal adherens junctions.
Enables actin filament binding activity and beta-catenin binding activity. Involved in several processes, including cortical actin cytoskeleton organization; embryonic morphogenesis; and regulation of actin cytoskeleton organization. Located in adherens junction and apical junction complex. Part of catenin complex. Expressed in several structures, including distal tip cell; germ cell; intestinal cell; neuroblasts; and pharyngeal cell. Human ortholog(s) of this gene implicated in several diseases, including arrhythmogenic right ventricular dysplasia 13; cervix uteri carcinoma in situ; and urinary system cancer (multiple). Is an ortholog of human CTNNA2 (catenin alpha 2).
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.
