GT5 — Lactuca sativa

Summary

GT5 (LSAT_V11C500270050) on garden lettuce chromosome 5 encodes a UDP-glycosyltransferase family protein with UDP-glucosyltransferase and UDP-glycosyltransferase activity. The gene product is associated with multiple glucosyltransferase activities including those acting on flavones, flavonones, isoflavones, quercetin, anthocyanins, abscisic acid, indole-3-acetate, cinnamate, sinapate, gallate, and 4-hydroxybenzoate. GT5 is linked to biological processes including anthocyanin anabolism, protocatechuate and cinnamic acid ester metabolism, ferulate metabolism, abscisic acid signaling and response, negative regulation of response to water deprivation, and regulation of abscisic acid-mediated signaling. It is associated with fruit ripening, seed development, seed germination, and leaf development. The protein localizes to the cytoplasm and nucleus. Related genes in other species include UGT84A23 and UGT84A24, which are linked to hydroxybenzoate glucosylation.
