Summary

TMEM131 (transmembrane protein 131, HGNC:30366) is a protein-coding gene on chromosome 2q11.2, encoding Transmembrane protein 131 (Q92545). Collagen binding transmembrane protein involved in collagen secretion by recruiting the ER-to-Golgi transport complex TRAPPIII.

Enables collagen binding activity. Involved in collagen biosynthetic process. Predicted to be active in membrane.

Literature-anchored findings (GeneRIF, showing 1)

  • A statistically significant loss of methylation at CpG dinucleotide sites within the non-syntenic TMEM131 gene is observed in individuals with free trisomy 21 (Down syndrome) compared with control disomic samples. The loss is independent of the maternal or the paternal origin of the chromosome 21 nondisjunction event. (PMID:27100087)

Function. Collagen binding transmembrane protein involved in collagen secretion by recruiting the ER-to-Golgi transport complex TRAPPIII. May play a role in the immune response to viral infection.

Subunit / interactions. Interacts (via PapD-L domain) with COL1A2 (via C-terminus); the interaction is direct, may occur with other collagen proteins, and is involved in assembly and TRAPPIII ER-to-Golgi transport complex-dependent secretion of collagen. Interacts (via C-terminus) with TRAPPC8 (via C-terminus); the interaction is direct.

Subcellular location. Membrane.

Domain organisation. Possesses a PapD-like (PapD-L) domain similar to PapD domains involved in assembly and secretion of bacterial pilus components. The PapD-L domain can bind collagens and is probably involved in collagen assembly and secretion.

Similarity. Belongs to the TMEM131 family.
