Enables several functions, including inositol 1,4,5 trisphosphate binding activity; phosphatidylinositol phospholipase C activity; and phospholipid binding activity. Involved in several processes, including positive regulation of cytosolic calcium ion concentration involved in phospholipase C-activating G protein-coupled signaling pathway; positive regulation of inositol trisphosphate biosynthetic process; and positive regulation of norepinephrine secretion. Located in several cellular components, including cytosol; membrane raft; and mitochondrial membrane. Used to study congestive heart failure and hypertension. Biomarker of hypertension. Human ortholog(s) of this gene implicated in nonsyndromic congenital nail disorder 3. Orthologous to human PLCD1 (phospholipase C delta 1). [provided by Alliance of Genome Resources, Apr 2022]
