PABPC4

PABPC4 is a protein found in human cells that binds to poly(A) tails—strings of adenine nucleotides—on messenger RNA (mRNA). Its main role is to help regulate how stable and available mRNA molecules are for protein production. By doing so, PABPC4 influences the efficiency of translating genetic instructions into proteins, which are essential for cell function. It is part of a family of similar proteins that coordinate the life cycle of mRNA, impacting processes like gene expression, cell growth, and response to signals.
