WIG — Arabidopsis thaliana

Summary

AT5G40280 (WIG/ERA1) encodes a protein with protein farnesyltransferase, geranylgeranyltransferase, and prenyltransferase activities that belongs to the PGGT1B-like family. The gene is associated with abscisic acid signaling and response, drought tolerance, stomatal regulation and closure, and transpirational water loss. It has been linked to meristem development and determinacy, floral organ size and number, carpel number, fruit diameter and size, seed yield, seed size and number, seed fatty acid composition and protein content, root length and hair length, stem elongation, flowering time, disease tolerance and resistance, brassinosteroid sensitivity, glucose signaling, pollen germination, ovule development, and cuticle development. The protein localizes to the nucleus and the protein farnesyltransferase complex, and is associated with protein prenylation, lipid modification, and response to water and osmotic stress.
