Taxonomic identifier

44689 [NCBI]

Taxonomic lineage

Eukaryota › Amoebozoa › Mycetozoa › Dictyosteliida › Dictyostelium

Protein attributes

Sequence length	438 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 membrane phospholipids, such as PtdCho (phosphatidylcholine), producing the free headgroup and PtdOH (phosphatidic acid; signaling molecule on its own) By similarity.
Catalytic activity	A phosphatidylcholine + H2O = choline + a phosphatidate.
Enzyme regulation	Inhibited by butan-1-ol.
Developmental stage	Expression is observed in spores, increases about two- to three-fold at 0.5 hour to 1 hour during spore germination, and then rapidly decreases. The mRNA is not detectable in vegetative cells or in early multicellular development on filters, but is present late during development, approximately at the time of sporulation. Ref.2
Sequence similarities	Belongs to the phospholipase D family. Contains 2 PLD phosphodiesterase domains.
Sequence caution	The sequence AAA67429.1 differs from that shown. Reason: Erroneous gene model prediction.
