PIN1 — Medicago truncatula

Summary

MTR_8G076070 (symbol PIN1, preferred name MtPIN1AT) on barrel medic chromosome 8 encodes a protein with PPIase_Pin1 and PPIase_PpiC domains, possessing cis-trans proline isomerase activity and protein binding capability. The gene is associated with auxin polar transport, leaflet formation, lateral root formation, flower development, seed development, and regulation of seed size. It has been linked to root gravitropism, flowering time, protein folding, and prolyl cis/trans isomerization. The encoded product localizes to the nucleus, cytosol, endoplasmic reticulum, mitochondria, and plasmodesmata. Studies of related genes in other species link the family to strigolactone signaling. Associations with amino acid content and seed size have also been noted.
