Protein attributes

Sequence length	810 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Hydrolyzes glycerol-phospholipids at the terminal phosphodiesteric bond. Plays an important role in various cellular processes, including phytohormone action, vesicular trafficking, secretion, cytoskeletal arrangement, meiosis, tumor promotion, pathogenesis, membrane deterioration and senescence.
Catalytic activity	A phosphatidylcholine + H2O = choline + a phosphatidate.
Cofactor	Calcium. Calcium requirement for activity depends on pH. Active either under acidic conditions with micromolar levels of calcium (PIP2-dependent) or at neutral pH with millimolar levels of calcium (PIP2-independent).
Subcellular location	Cytoplasm By similarity. Membrane; Peripheral membrane protein By similarity.
Domain	C2 domain is a calcium-binding fold, and the binding promotes the protein association with membranes. A lower affinity toward calcium can be anticipated for PLD alpha due to the absence of two potential calcium ligands.
Miscellaneous	The propeptide appears to play a key role in the proper folding and activation of the enzyme.
Sequence similarities	Belongs to the phospholipase D family. C2-PLD subfamily. Contains 1 C2 domain. Contains 2 PLD phosphodiesterase domains.
