Summary
Predicted to enable mRNA binding activity. Involved in post-transcriptional regulation of gene expression; sperm axoneme assembly; and sperm individualization. Located in nuclear speck. Orthologous to human KHDRBS2 (KH RNA binding domain containing, signal transduction associated 2) and KHDRBS3 (KH RNA binding domain containing, signal transduction associated 3).
