Phospholipase D B

Gene

pldB

Organism
Dictyostelium discoideum (Slime mold)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at transcript leveli

Functioni

Plays a role in cell growth. Hydrolyzes membrane phospholipids, such as PtdCho (phosphatidylcholine), producing the free headgroup and PtdOH (phosphatidic acid; signaling molecule on its own). Involved in the inhibition of actin-based motility and endocytosis. Its inhibition causes complete collapse of F-actin organization. Plays an important role in cell migration by localizing along the anterior cell membrane. Overexpression leads to the inability to aggregate even at higher cell density. Also known as a negative regulator of quorum sensing.4 Publications

Catalytic activityi

A phosphatidylcholine + H2O = choline + a phosphatidate.

Enzyme regulationi

Inhibited by butan-1-ol.1 Publication

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
