Enables mRNA 3'-UTR binding activity. Involved in male meiotic nuclear division; negative regulation of MAPK cascade; and spermatogenesis. Located in P granule and nuclear periphery. Expressed in several structures, including P3.p hermaphrodite; P4.p hermaphrodite; germ line; sperm; and vulva. Used to study obesity. Human ortholog(s) of this gene implicated in cerebellar ataxia type 47. Is an ortholog of human PUM1 (pumilio RNA binding family member 1) and PUM2 (pumilio RNA binding family member 2).
Involved in positive regulation of miRNA processing and positive regulation of stem cell differentiation. Located in cytoplasm and nucleoplasm. Expressed in seam cell; uterus; and vulva. Is an ortholog of human CD2BP2 (CD2 cytoplasmic tail binding protein 2).
Predicted to enable U2 snRNA binding activity. Predicted to be involved in mRNA splicing, via spliceosome. Predicted to be located in nucleus. Predicted to be part of U2 snRNP. Is an ortholog of human SF3B3 (splicing factor 3b subunit 3).
