V-type proton ATPase subunit F (ATP6V1F)

The protein contains 119 amino acids for an estimated molecular weight of 13370 Da.

 

Subunit of the peripheral V1 complex of vacuolar ATPase essential for assembly or catalytic function. V-ATPase is responsible for acidifying a variety of intracellular compartments in eukaryotic cells. (updated: March 4, 2015)

CLONING

The vacuolar ATPase (V-ATPase) is a multisubunit complex that mediates acidification of intracellular organelles. By large-scale sequencing of a human fetal brain cDNA library and database searching, Fujiwara et al. (1995) identified a sequence showing homology with the 14-kD subunit of M. sexta V-ATPase. Using 5-prime RACE, they cloned a full-length cDNA encoding a deduced 119-amino acid protein with a molecular mass of 14 kD. The protein is predominantly hydrophilic and shares 69% and 70% sequence identity with the M. sexta and Drosophila homologs, respectively. Northern blot analysis detected ubiquitous expression of a 0.8-kb transcript. ... More on the omim web site
