Genes affected

MBOAT4 (HGNC:32311): (membrane bound O-acyltransferase domain containing 4) Enables serine O-acyltransferase activity. Involved in peptidyl-serine octanoylation. Predicted to be located in endoplasmic reticulum. Predicted to be active in membrane. Predicted to be integral component of endoplasmic reticulum membrane. [provided by Alliance of Genome Resources, Apr 2022]

LEPROTL1 (HGNC:6555): (leptin receptor overlapping transcript like 1) Enables identical protein binding activity. Predicted to be involved in late endosome to vacuole transport via multivesicular body sorting pathway and negative regulation of growth hormone receptor signaling pathway. Predicted to be integral component of membrane. Predicted to be active in endosome. [provided by Alliance of Genome Resources, Apr 2022]
