Phospholipase that may play a role in phospholipids remodeling. May selectively cleave myristate (C14)-containing phosphatidylcholines through its predominant phospholipase 1 activity, cleaving preferentially acyl groups in sn1 position. In parallel, may have a minor phospholipase 2 activity acting on acyl groups in position sn2. In addition to (C14)-containing phosphatidylcholines, may also act on other medium-chain-containing and oxidatively truncated phospholipids. a 1,2-diacyl-sn-glycero-3-phosphocholine + H2O = a 1-acyl-sn-glycero-3-phosphocholine + a fatty acid + H(+) a 1,2-diacyl-sn-glycero-3-phosphocholine + H2O = a 2-acyl-sn-glycero-3-phosphocholine + a fatty acid + H(+) 1-tetradecanoyl-2-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phosphocholine + H2O = 2-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phosphocholine + H(+) + tetradecanoate 1-tetradecanoyl-2-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phosphocholine + H2O = (9Z,12Z)-octadecadienoate + 1-tetradecanoyl-sn-glycero-3-phosphocholine + H(+) 1-tetradecanoyl-2-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phosphocholine + H2O = 2-(5Z,8Z,11Z,14Z)-eicosatetraenoyl-sn-glycero-3-phosphocholine + H(+) + tetradecanoate 1-tetradecanoyl-2-(4Z,7Z,10Z,13Z,16Z,19Z-docosahexaenoyl)-sn-glycero-3-phosphocholine + H2O = 2-(4Z,7Z,10Z,13Z,16Z,19Z-docosahexaenoyl)-sn-glycero-3-phosphocholine + H(+) + tetradecanoate 1,2-ditetradecanoyl-sn-glycero-3-phosphocholine + H2O = 2-tetradecanoyl-sn-glycero-3-phosphocholine + H(+) + tetradecanoate 1-octadecanoyl-2-acetyl-sn-glycero-3-phosphocholine + H2O = 1-octadecanoyl-sn-glycero-3-phosphocholine + acetate + H(+) 1,2-ditetradecanoyl-sn-glycero-3-phosphocholine + H2O = 1-tetradecanoyl-sn-glycero-3-phosphocholine + H(+) + tetradecanoate 1-octadecanoyl-2-pentanoyl-sn-glycero-3-phosphocholine + H2O = 1-octadecanoyl-sn-glycero-3-phosphocholine + H(+) + pentanoate 1-octadecanoyl-2-hexanoyl-sn-glycero-3-phosphocholine + H2O = 1-octadecanoyl-sn-glycero-3-phosphocholine + H(+) + hexanoate 1-octadecanoyl-2-octanoyl-sn-glycero-3-phosphocholine + H2O = 1-octadecanoyl-sn-glycero-3-phosphocholine + H(+) + octanoate 1-octadecanoyl-2-nonanoyl-sn-glycero-3-phosphocholine + H2O = 1-octadecanoyl-sn-glycero-3-phosphocholine + H(+) + nonanoate 1-O-hexadecyl-2-nonadioyl-sn-glycero-3-phosphocholine + H2O = 1-O-hexadecyl-sn-glycero-3-phosphocholine + H(+) + nonanedioate 1-hexadecanoyl-2-nonadioyl-sn-glycero-3-phosphocholine + H2O = 1-hexadecanoyl-sn-glycero-3-phosphocholine + H(+) + nonanedioate 1-hexadecanoyl-2-(9-oxononanoyl)-sn-glycero-3-phosphocholine + H2O = 1-hexadecanoyl-sn-glycero-3-phosphocholine + 9-oxononanoate + H(+) 1-hexadecanoyl-2-(5-oxopentanoyl)-sn-glycero-3-phosphocholine + H2O = 1-hexadecanoyl-sn-glycero-3-phosphocholine + 5-oxopentanoate + H(+) 1-hexadecanoyl-2-glutaroyl-sn-glycero-3-phosphocholine + H2O = 1-hexadecanoyl-sn-glycero-3-phosphocholine + glutarate + H(+) 1-O-hexadecyl-2-acetyl-sn-glycero-3-phosphocholine + H2O = 1-O-hexadecyl-sn-glycero-3-phosphocholine + acetate + H(+) Widely expressed with higher expression in liver.
