ani-1 encodes one of three C. elegans anillins; ANI-1 activity is required in the early embryo for cortical contractile events, including polar body extrusion, membrane ruffling, and pseudocleavage; at later stages of development, ANI-1 also plays a role in cuticle formation, coordinated locomotion, vulval development, and male tail formation; in regulating cortical events, ANI-1 appears to function by positively regulating septin (UNC-59 and UNC-61) localization to the contractile ring as well as formation of septin- and NMY-2-containing cortical patches; in telophase embryos, ANI-1 localizes to the cell cortex and cleavage furrow.
Enables actin filament binding activity; microtubule binding activity; and small GTPase binding activity. Involved in several processes, including first cell cycle pseudocleavage; nematode male tail tip morphogenesis; and organelle organization. Located in several cellular components, including cleavage furrow; growth cone; and midbody. Expressed in several structures, including QL.a; QL.pa; germ line; neuroblasts; and neurons. Human ortholog(s) of this gene implicated in focal segmental glomerulosclerosis 8. Is an ortholog of human ANLN (anillin, actin binding protein).
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.
