ELG — Solanum tuberosum

Summary

PGSC0003DMG400027536, the potato gene ELG (also known as SERK1) on chromosome 4, encodes a non-specific serine/threonine protein kinase with leucine-rich repeat domains and a transmembrane receptor serine/threonine kinase activity. The product has coreceptor activity, signaling receptor activity, steroid binding, SNARE binding, and exhibits protein kinase, homodimerization, and heterodimerization activities. ELG is associated with somatic embryogenesis, tissue morphogenesis, regulation of developmental growth and cell growth, skotomorphogenesis, and embryogenesis. It is linked to immune complex formation, the MAPK cascade, metabolic burst, upregulation of innate immune response, and regulation of defence response to fungi. The gene is also associated with response to virus, virus-induced PTGS, detection of brassinosteroid stimulus, carbohydrate and hormone anabolism, and microtubule bundling. ELG localizes to the membrane, plasmalemma, endosome, and macromolecule complex. Related genes in other species link the family to brassinosteroid signaling and immune responses.
