Transmembrane protein 175, or TMEM175, is a transmembrane protein that is thought to be an endolysosomal potassium channel. It is predicted to have many orthologs across eukaryotes.
Expression
[edit]Based on human and mouse EST profiles and a human tissue GEO profile, TMEM175 appears to be expressed at a relatively high level (75-98%) in normal tissues.[1][2] TMEM175 appears to be down regulated in stage three ovarian cancer.[3]
Homology
[edit]Transmembrane protein 175 has no paralogs. It does have orthologs within eukaryotes. The following table presents some of the orthologs found using searches in BLAST[4] and BLAT.[5] This list does not contain all of the orthologs for TMEM175. It is meant to display the diversity of species for which orthologs are found.

Predicted Post-Translational Modification
[edit]Using various tools at ExPASy[6] the following are possible post-translational modifications for TMEM175.
- 5 possible CK2 phosphorylation sites
- 2 possible PKC phosphorylation sites
- N-myristoylation sites around transmembrane regions
The N-myristoylation sites are conserved in vertebrates.
