SKP1 — Medicago truncatula

Summary

MTR_4G032500, the SKP1 gene of barrel medic (Medicago truncatula) on chromosome 4, encodes a SKP1-like protein containing a Skp1 component dimerisation domain and a POZ domain. The product binds cullin family proteins and is associated with protein ubiquitination, particularly SCF-dependent proteasomal ubiquitin-dependent protein breakdown. The gene is associated with cell cycle, cell division, cell motility, secretion, jasmonic acid signalling, homeostasis, and the development of leaves, flowers, and organs. It localises to both the cytoplasm and nucleus. Associations with leaf size have also been noted. Related genes in other species link the SKP1 family to similar ubiquitination and developmental processes.
