ATM4 — Lactuca sativa

Summary

LsATM4, also known as ATM4, on lettuce chromosome 4 encodes a protein with a MYB domain and SANT/Myb domain, and has DNA binding, sequence-specific DNA binding, DNA binding transcription factor activity, transcription cis-regulatory region binding, protein dimerization activity, chromatin binding, protein binding, kinase binding, phosphatase binding, BHLH transcription factor binding, ERK1 binding, calcium ion binding, and protein kinase activity. It is associated with regulation of raffinose metabolic process, cellular detoxification of cadmium ion, cellular response to sulfur starvation, regulation of glucosinolate biosynthetic process, regulation of proanthocyanidin anabolism, regulation of trichome morphogenesis, regulation of flavonoid anabolism, trichome spacing, plant epidermal cell fate specification, regulation of defense response to insect, drought recovery, regulation of primary metabolic process, cutin anabolism, and positive regulation of anthocyanin anabolism. It localizes to the nucleus, cytosol, root hair, preprophase band, cell cortex, and TGN. Associations with traits include leaf trichome density, seed protein content, phosphorus response, iron concentration, photoperiod-sensitive flowering time, branch angle, and many others. Related genes in other species are linked to glucosinolate accumulation, cuticle development, suberin biosynthesis, and drought response.
