Protein attributes

Sequence length	83 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	This protein is one of the chains of the nonenzymatic membrane component (F0) of mitochondrial ATPase.
Subunit structure	F-type ATPases have 2 components, CF1 - the catalytic core - and CF0 - the membrane proton channel. CF1 has five subunits: alpha3, beta3, gamma1, delta1, epsilon1. CF0 has three main subunits: a, b and c.
Subcellular location	Mitochondrion membrane; Multi-pass membrane protein Potential.
Sequence similarities	Belongs to the ATPase C chain family.
