Summary: This gene encodes a type I transmembrane glycoprotein that is an integral component of the multimeric gamma-secretase complex. The encoded protein cleaves integral membrane proteins, including Notch receptors and beta-amyloid precursor protein, and may be a stabilizing cofactor required for gamma-secretase complex assembly. The cleavage of beta-amyloid precursor protein yields amyloid beta peptide, the main component of the neuritic plaque and the hallmark lesion in the brains of patients with Alzheimer's disease; however, the nature of the encoded protein's role in Alzheimer's disease is not known for certain. Mutations in this gene are associated with familial acne inversa. A pseudogene of this gene is present on chromosome 21. Alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined. [provided by RefSeq, Feb 2014]

The impaired EGFR signaling and its effects on epidermal differentiation were also observed in familial AI patients and Ncstn(DeltaKC) mice. Thus, our study showed that miR-30a-3p/RAB31/EGFR signaling pathway may play a key role in the pathogenesis of familial AI with NCSTN mutations.

The results show no differences in the decreased levels of inflammatory factors between patients with and without NCSTN mutations. This result may indicate that NCSTN mutations have no direct effect on inflammatory cells in the process of cytokine production.

The authors identified two nonsynonymous mutations in NCSTN in a white population, one of which had previously been described in African American and Chinese patients with HS. In addition, several intronic polymorphisms within the NCSTN were identified that were present at a significantly higher frequency in the HS population.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

See identical proteins and their annotated locations for NP_001277113.1

Status: REVIEWED

Description

Transcript Variant: This variant (2) has a different 5' structure resulting in translation initiation at an alternate AUG compared to variant 1; the 5'-most AUG, as used in variant 1, is associated with a truncated ORF that would render the transcript a candidate for nonsense-mediated decay (NMD). Leaky scanning may allow translation initiation at the alternate AUG resulting in a shorter isoform (2) with a distinct N-terminus compared to isoform 1.
