Summary: Predicted to enable RNA binding activity. Involved in several processes, including gonad development; positive regulation of cell migration; and regulation of Wnt signaling pathway. Located in cytoplasm and nucleus. Part of spliceosomal complex. Is expressed in several structures, including germ line; hermaphrodite gonad; hypodermal cell; intestine; and vulva. Orthologous to human CACTIN (cactin, spliceosome C complex subunit). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

CACN-1 is needed in the soma for proper germ line development and maturation. When CACN-1 is depleted, sheath cells are absent and/or abnormal. CACN-1 is part of a protein network that influences somatic gonad development and function through alternative splicing or post-transcriptional gene regulation.
Title: CACN-1 is required in the Caenorhabditis elegans somatic gonad for proper oocyte development.
RNAi depletion experiments and analysis of the hypomorphic allele cacn-1 indicate that CACN-1 is required during distal tip cells migration for proper pathfinding and for cessation of distal tip cells migration at the end of larval morphogenesis.
Title: CACN-1/Cactin interacts genetically with MIG-2 GTPase signaling to control distal tip cell migration in C. elegans.
