TMEM9 (IPR008853)

Short name: TMEM9

Overlapping homologous superfamilies


Family relationships



This family contains several eukaryotic transmembrane proteins which are homologous to Homo sapiens transmembrane protein 9 Q9P0T7. The TMEM9 gene encodes a 183 amino-acid protein that contains an N-terminal signal peptide, a single transmembrane region, three potential N-glycosylation sites and three conserved cys-rich domains in the N terminus, but no known functional domains. The protein is highly conserved between species from Caenorhabditis elegans to H. sapiens and belongs to a novel family of transmembrane proteins. The exact function of TMEM9 is unknown although it has been found to be widely expressed and localised to the late endosomes and lysosomes [PMID: 12359240]. Members of this family contain CXCXC repeats IPR004153 in their N-terminal region.
