About Lpar1

Primary_assembly 5: 73,229,625-73,369,895 reverse strand.mRatBN7.2:CM026978.1

This gene has 1 transcript (splice variant), 216 orthologues, 18 paralogues and is associated with 15 phenotypes. Biased expression in Brain (RPKM 71.1), Uterus (RPKM 44.2) and 8 other tissues.

Summary

Enables G-protein alpha-subunit binding activity and phospholipid binding activity. Involved in several processes, including cellular response to 1-oleoyl-sn-glycerol 3-phosphate; negative regulation of cAMP-mediated signaling; and nervous system development. Located in several cellular components, including dendrite; neuronal cell body; and plasma membrane. Used to study hepatocellular carcinoma and transient cerebral ischemia. Orthologous to human LPAR1 (lysophosphatidic acid receptor 1). [provided by Alliance of Genome Resources, Apr 2022]
