HSP18.2 — Brassica oleracea var. botrytis

Summary

BoHSP18.2 (HSP18.2) on cauliflower chromosome 3 encodes a small heat shock protein (sHSP) belonging to the HSP20-like chaperone family, with a Small_HSP domain and A-crystallin/Hsp20_dom. The encoded protein exhibits glycolipid binding, chloroplast targeting sequence receptor activity, identical protein binding, and protein binding functions. It is associated with responses to heat, cold, hydrogen peroxide, ethanol, copper, arsenic, cadmium, and salinity, as well as protein folding, stabilization, oligomerization, and chloroplast targeting. The gene is linked to heat stress response, heat shock response, and flower development. Associations include traits such as chloroplast development, flowering time, disease tolerance, plant growth and development, and root morphology. The protein localizes to the chloroplast outer membrane, plasma membrane, cytoplasm, and nucleus. Related genes in other species are linked to protein translation efficiency and transgene expression.
