BIP1 — Daucus carota subsp. sativus

Summary

DCAR_008954 (symbol BIP1, also known as DcHSP70) on carrot chromosome 3 encodes a member of the Hsp70 family of molecular chaperones, with ATP hydrolase activity, ATP binding, heat shock protein binding and protein folding chaperone functions. The gene is associated with protein folding in the endoplasmic reticulum, the ERAD pathway, the ER unfolded protein response, homologous recombination, and protein refolding. It is linked to pollen development, pollen germination and pollen tube growth. The encoded protein localises to the ER chaperone complex, ER lumen, membrane, cytoplasm and nucleus. Related genes in other species link the family to fruit length, seed weight, seed size, lignin content, stomatal resistance, chlorophyll content and plant height.
