Summary: Enables actin binding activity; protein phosphatase 1 binding activity; and protein phosphatase activator activity. Involved in several processes, including enteric nervous system development; morphogenesis of embryonic epithelium; and negative regulation of integrin-mediated signaling pathway. Located in lamellipodium. Is expressed in several structures, including 1st branchial arch mandibular component; central nervous system; facial prominence; and retina. Orthologous to human PHACTR4 (phosphatase and actin regulator 4). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
