This gene encodes a protein that has been associated with several biological functions including cellular magnesium uptake, protein glycosylation and embryonic development. This protein localizes to the endoplasmic reticulum and acts as a component of the oligosaccharyl transferase complex which is responsible for N-linked protein glycosylation. This gene is a candidate tumor suppressor gene. Homozygous mutations in this gene are associated with autosomal recessive nonsyndromic mental retardation-7 and in the proliferation and invasiveness of several cancers including metastatic pancreatic cancer, ovarian cancer and glioblastoma multiform.

Forensic Context
A study in mice demonstrated that chronic methamphetamine administration significantly dysregulates the TUSC3 in microglia, where it is involved in the protein processing of endoplasmic reticulum pathway [Oladapo et al. DOI:10.3390/Ijms26020649].
