About TMTC2

Cytogenetic location: 12q21.31 Genomic coordinates (GRCh38): 12:82,686,906-83,134,866 (from NCBI)

This gene has 5 transcripts (splice variants), 288 orthologues and 14 paralogues. Ubiquitous expression in brain (RPKM 7.5), gall bladder (RPKM 7.0) and 24 other tissues.

Summary

The protein encoded by this gene is an integral membrane protein localized to the endoplasmic reticulum (ER). The encoded protein contains many tetratricopeptide repeats, sequences known for being involved in protein-protein interactions. This protein binds both the calcium uptake pump SERCA2B and the carbohydrate-binding chaperone calnexin, and it appears to play a role in calcium homeostasis in the ER. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2016]
