* Information From OMIM

Function: Interaction of phospholipase D (see PLD1; OMIM:602382) with actin microfilaments regulates cell proliferation, vesicle trafficking, and secretion. Kusner et al. (2002) found that highly purified globular actin (G-actin) inhibited both basal and stimulated PLD1 activity, whereas filamentous actin (F-actin) had the opposite effect. Actin-induced modulation of PLD1 activity was independent of the activating stimulus. The effects of actin on PLD1 were isoform specific: human platelet actin, which exists in a 5:1 ratio of beta- and gamma-actin, was only 45% as potent and 40% as efficacious as rabbit skeletal muscle alpha-actin.
