Summary: Enables protein tyrosine phosphatase activity. Involved in integrin-mediated signaling pathway; modulation of chemical synaptic transmission; and regulation of focal adhesion assembly. Acts upstream of or within insulin receptor signaling pathway and protein phosphorylation. Located in focal adhesion and membrane. Is active in Schaffer collateral - CA1 synapse. Is integral component of synaptic membrane. Is expressed in several structures, including adrenal gland; central nervous system; decidua; extraembryonic component; and future brain. Orthologous to human PTPRA (protein tyrosine phosphatase receptor type A). [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.

See identical proteins and their annotated locations for NP_001157160.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) lacks an alternate in-frame exon in the 5' coding region, compared to variant 1. This results in a shorter protein (isoform 2), compared to isoform 1.
