Protein attributes

Sequence length	74 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
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.
Catalytic activity	ATP + H2O + H+(In) = ADP + phosphate + H+(Out).
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.
Caution	The first citation (Ref.1) originated from Petunia.
RNA editing	Edited at positions 7, 20, 28, 31, 64, 71 and 75. The stop codon at position 75 is created by RNA editing (By similarity).
