OverviewNCBI Gene
This gene encodes a phospholipase enzyme that catalyzes the hydrolysis of phosphatidylinositol-4,5-bisphosphate to generate two second messengers: inositol 1,4,5-triphosphate (IP3) and diacylglycerol (DAG). These second messengers subsequently regulate various processes affecting cell growth, differentiation, and gene expression. This enzyme is regulated by small monomeric GTPases of the Ras and Rho families and by heterotrimeric G proteins. In addition to its phospholipase C catalytic activity, this enzyme has an N-terminal domain with guanine nucleotide exchange (GEF) activity. Mutations in this gene cause early-onset nephrotic syndrome; characterized by proteinuria, edema, and diffuse mesangial sclerosis or focal and segmental glomerulosclerosis. Alternative splicing results in multiple transcript variants encoding distinct isoforms.[provided by RefSeq, Sep 2009]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads PLCE1 as an antibody target. Whether an autoantibody or antibody against PLCE1 could matter depends on whether native PLCE1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
PLCE1 is annotated at the cell surface, where native PLCE1 is exposed to circulating antibodies and is a prime autoantibody target that could block, deplete, or overstimulate it.
Annotation status
The present source text does not explicitly label PLCE1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
