Summary: Enables mitogen-activated protein kinase binding activity. Involved in several processes, including positive regulation of biosynthetic process; positive regulation of transport; and regulation of cellular extravasation. Predicted to be located in plasma membrane. Used to study several diseases, including acute kidney failure; neutropenia; perinatal necrotizing enterocolitis; pleurisy; and transient cerebral ischemia. Biomarker of conjunctivitis; sciatic neuropathy; and transient cerebral ischemia. Orthologous to human PTAFR (platelet activating factor receptor).

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.
