V-type proton ATPase subunit D (ATP6V1D)

Subunit of the peripheral V1 complex of vacuolar ATPase.

Vacuolar ATPase is responsible for acidifying a variety of intracellular compartments in eukaryotic cells, thus providing most of the energy required for transport processes in the vacuolar system (By similarity).

May play a role in cilium biogenesis through regulation of the transportation and the localization of proteins to the cilium. .
