PIN1 — Brassica juncea

Summary

BJUA06G13770S (PIN1, BjPIN1AT) on Indian mustard chromosome A06 encodes a peptidyl-prolyl cis-trans isomerase of the PPIase_Pin1 family, with cis-trans proline isomerase activity and protein binding capability. The gene is associated with auxin transport and polar auxin transport, regulation of protein localization, cell cycle modulation, geotropism, embryogenesis, and regulation of flower development. It has been linked to root gravitropism, flowering time, prolyl cis/trans isomerization, and protein folding. The product localizes to the nucleus, cytosol, endoplasmic reticulum, mitochondria, and plasmodesmata. Studies of the Arabidopsis relative link the family to strigolactone signaling, and sequence similarity connects the family to flowering time traits.
