Summary: Predicted to enable 1-alkyl-2-acetylglycerophosphocholine esterase activity; platelet-activating factor acetyltransferase activity; and protein dimerization activity. Acts upstream of or within spermatogenesis. Located in cytoplasm. Is expressed in several structures, including alimentary system; eye; genitourinary system; hemolymphoid system gland; and nervous system. Orthologous to human PAFAH1B3 (platelet activating factor acetylhydrolase 1b catalytic subunit 3). [provided by Alliance of Genome Resources, Apr 2022]

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.
