Summary: Enables signaling receptor activity. Involved in phosphatidylinositol 3-kinase/protein kinase B signal transduction; platelet aggregation; and positive regulation of platelet activation. Acts upstream of or within recognition of apoptotic cell. Located in phagocytic cup. Is active in plasma membrane. Is expressed in brain; dorsal root ganglion; embryo; heart; and spinal cord. Orthologous to human PEAR1 (platelet endothelial aggregation receptor 1). [provided by Alliance of Genome Resources, Nov 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.

Description

Transcript Variant: This variant (5) differs in the 5' UTR and uses an alternate splice junction at the 5' end of an exon, which causes translation initiation at an alternate start codon, compared to variant 1. The resulting isoform (b) is shorter at the N-terminus compared to isoform a.
