PIN1 — Brassica juncea

Summary

BJUB02G12020S (symbol PIN1, preferred name BjPIN1AT) on Indian mustard (Brassica juncea) chromosome B02 encodes a peptidyl-prolyl cis-trans isomerase (PPIase) of the Pin1 family, possessing cis-trans proline isomerase activity and protein binding capability. The gene is associated with auxin transport, polar auxin transport, regulation of protein localization, cell cycle modulation, geotropism, embryogenesis, and regulation of flower development. Its product localizes to the plasmodesma, endoplasmic reticulum, mitochondria, cytosol, and nucleus. Phenotypic associations include prolyl cis/trans isomerization, root gravitropism, flowering time, and protein folding. Studies of related genes in other species link the family to strigolactone signaling and flowering time traits.
