Gene_locus Report for: human-LYPLA1

Homo sapiens (Human) lysophospholipase I (LYPLA1) APT1, acyl-protein thioesterase 1 S-depalmitoylase

Previously characterized as lysophospholipase I, but has several hudred-fold higher activity as a protein thioesterase. Acyl protein thioesterase apt1, which catalyzes depalmitoylation of Galpha proteins and Ras. S-depalmitoylase found both in cytoplasm and mitochondria . A shorter form exists as a splice variant AF077199 nuc 4679011 pep 4679012 . Q9UQF9 probable isoform of same gene
