Enables calcium ion binding activity; identical protein binding activity; and phosphatidylinositol phospholipase C activity. Involved in several processes, including cellular response to glyceraldehyde; cellular response to ionomycin; and learning or memory. Located in cytosol; membrane; and nucleus. Biomarker of myocardial infarction. Human ortholog(s) of this gene implicated in Alzheimer's disease; developmental and epileptic encephalopathy 12; and myelodysplastic syndrome. Orthologous to human PLCB1 (phospholipase C beta 1). [provided by Alliance of Genome Resources, Apr 2022]
