CPT1 — Lactuca sativa

Summary

LsCPT1 (CPT1) on chromosome 2 of garden lettuce encodes a prenyltransferase with dimethylallylcistransferase, rubber cis-polyprenylcistransferase, dehydrodolichyl diphosphate synthase, and zFPS activities, and belongs to the UPP_synth-like family. The gene is associated with polyprenol anabolism, plastid membrane organization, virus-induced post-transcriptional gene silencing, and response to cold. Its product localizes to the chloroplast stroma, endoplasmic reticulum, and cytosol. Related genes in other species are linked to cis-polyisoprenoid, dolichol, and long-chain dolichol biosynthesis. Sequence similarity connections also associate the family with salt response and stomatal resistance traits.
