VGPC1_C

VGPC1_C
PFAM accession number:PF16799
Interpro abstract (IPR031844):

This entry represents the short C-terminal region of voltage-gated proton channel 1 proteins in higher eukaryotes. This domain is necessary for achieving the dimeric architecture, two monomers form a dimer via parallel alpha-helical coiled-coil interaction. This domain is also essential for localising the protein to an intracellular membrane [ (PUBMED:20147290) ].

This is a PFAM domain. For full annotation and more information, please see the PFAM entry VGPC1_C
