About SMPD4

Cytogenetic location: 2q21.1 Genomic coordinates (GRCh38): 2:130,151,392-130,181,757 (from NCBI)

This gene has 27 transcripts (splice variants), 206 orthologues and is associated with 2 phenotypes. Ubiquitous expression in bone marrow (RPKM 16.4), testis (RPKM 14.6) and 25 other tissues.

Summary

The protein encoded by this gene is a sphingomyelinase that catalyzes the hydrolysis of membrane sphingomyelin to form phosphorylcholine and ceramide. This gene is activated by DNA damage, cellular stress, and tumor necrosis factor, but it is downregulated by wild-type p53. The encoded protein localizes to the endoplasmic reticulum and Golgi network. [provided by RefSeq, Mar 2017]
