PIN1 — Cucumis sativus

Summary

CSA_4G046790, designated PIN1 (also CsPIN1, PIN1AT), encodes a peptidyl-prolyl cis-trans isomerase (EC 5.2.1.8) belonging to the PPIase_Pin1 family, with cis-trans proline isomerase, DNA-binding and protein-binding activities. In cucumber, this gene is associated with auxin polar transport, auxin signaling and anabolism, response to gravity and geotropism, regulation of flower development, cell division and cell cycle modulation, rRNA processing, and regulation of protein localization. It localises to the nucleus, cytosol, endoplasmic reticulum, plasmodesmata and mitochondria. The gene has been linked to fruit length and low temperature stress response. Studies of related genes in other species connect the family to prolyl cis/trans isomerization, root gravitropism, protein folding and flowering time, and leaf initiation.
