The protein encoded by this gene is a HEAT-like repeat-containing protein. The HEAT repeat is a tandemly repeated, 37-47 amino acid long module occurring in a number of cytoplasmic proteins. Arrays of HEAT repeats form a rod-like helical structure and appear to function as protein-protein interaction surfaces. The repeat-containing region of this protein has some similarity to the constant regulatory domain of the protein phosphatase 2A PR65/A subunit. The function of this particular gene product has not been determined. Alternative splicing has been observed for this gene and two transcript variants encoding distinct isoforms have been identified.

PPP4R4 has several biochemical functions, for example, protein binding, protein phosphatase regulator activity. Some of the functions are cooperated with other proteins, some of the functions could acted by PPP4R4 itself. We selected most functions PPP4R4 had, and list some proteins which have the same functions with PPP4R4. You can find most of the proteins on our site.
