TMEM100

 TMEM100
PFAM accession number:PF16311
Interpro abstract (IPR032536):

Transmembrane protein 100 (TMEM100) is a two-transmembrane protein highly conserved in vertebrates. It acts as an ALK1 receptor signalling-dependent protein during endothelial differentiation and vascular morphogenesis, and regulates TRPA1-TRPV1 complex that mediates pain signals in dorsal root ganglia neurons [ (PUBMED:22783020) (PUBMED:25640077) ].

This is a PFAM domain. For full annotation and more information, please see the PFAM entry TMEM100
