Protein attributes

Sequence length	763 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Hydrolyzes lysophosphatidic acid (LPA). Facilitates axonal outgrowth during development and regenerative sprouting. In the outgrowing axons acts as an ecto-enzyme and attenuates phospholipid-induced axon collapse in neurons and facilitates outgrowth in the hippocampus. Ref.1
Catalytic activity	A 1,2-diacylglycerol 3-phosphate + H2O = a 1,2-diacyl-sn-glycerol + phosphate.
Subcellular location	Membrane; Multi-pass membrane protein Potential.
Tissue specificity	Specifically expressed in neurons. Ref.1
Sequence similarities	Belongs to the PA-phosphatase related phosphoesterase family.
Sequence caution	The sequence BAA32300.3 differs from that shown. Reason: Erroneous initiation. The sequence CAI22799.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence EAW72991.1 differs from that shown. Reason: Erroneous gene model prediction.
