ATP/GTP Binding Protein Like Protein 5 (AGBL5)

AGBL5 has a function in the processing of cytosolic proteins such as alpha tubulin, which is known to be modified by the removal of a C terminal tyrosine. It is expressed in the brain. There are three named isoforms.

All CCPs are abundant in testis and also expressed in brain, pituitary, eye, and other mouse tissues. In brain, Nna1/CCP1, CCP5, and CCP6 are broadly distributed, whereas CCP2 and 3 exhibit restricted patterns of expression. Nna1/CCP1, CCP2, CCP5, and CCP6 were found to exhibit a cytosolic distribution, with a slight accumulation of CCP5 in the nucleus. Nna1/CCP1 and CCP2–6 function in the processing of cytosolic proteins such as alpha-tubulin, which is known to be modified by the removal of a C-terminal tyrosine.
