Small integral membrane protein 14

Small integral membrane protein 14, also known as SMIM14 or C4orf34, is a protein encoded on chromosome 4 of the human genome by the SMIM14 gene. SMIM14 has at least 298 orthologs mainly found in jawed vertebrates and no paralogs. SMIM14 is classified as a type I transmembrane protein. While this protein is not well understood by the scientific community, the transmembrane domain of SMIM14 may be involved in ER retention.
