Sphingomyelin Phosphodiesterase 3

SMPD3 (Sphingomyelin Phosphodiesterase 3) is a Protein Coding gene. Diseases associated with SMPD3 include Deafness, Autosomal Recessive 89. Among its related pathways are TNF signaling (REACTOME) and Metabolism. Gene Ontology (GO) annotations related to this gene include sphingomyelin phosphodiesterase activity.

Sphingomyelin Phosphodiesterase 3; Neutral Sphingomyelinase II; Neutral Sphingomyelinase 2; NSMase-2; NSMASE2; Sphingomyelin Phosphodiesterase 3, Neutral Membrane (Neutral Sphingomyelinase II); EC 3.1.4.12;

Catalyzes the hydrolysis of sphingomyelin to form ceramide and phosphocholine. Ceramide mediates numerous cellular functions, such as apoptosis and growth arrest, and is capable of regulating these 2 cellular events independently. Also hydrolyzes sphingosylphosphocholine. Regulates the cell cycle by acting as a growth suppressor in confluent cells. Probably acts as a regulator of postnatal development and participates in bone and dentin mineralization (PubMed:10823942, PubMed:14741383, PubMed:15051724).
Binds to anionic phospholipids (APLs) such as phosphatidylserine (PS) and phosphatidic acid (PA) that modulate enzymatic activity and subcellular location. May be involved in IL-1-beta-induced JNK activation in hepatocytes (By similarity).
May act as a mediator in transcriptional regulation of NOS2/iNOS via the NF-kappa-B activation under inflammatory conditions (By similarity).
