SKP1 — Medicago truncatula

Summary

MTR_1G112590 (SKP1) in barrel medic (Medicago truncatula) on chromosome 1 encodes a SKP1-like protein, a component of the SKP1/BTB/POZ superfamily that binds cullin family proteins. This gene is associated with protein ubiquitination and SCF-dependent proteasomal ubiquitin-dependent protein breakdown, as well as cell cycle, cell division, and cell motility. It has been linked to organ growth, leaf development, flower development, and leaf size, along with secretion, jasmonic acid (JA) signaling, and homeostasis. The encoded product localizes to both the cytoplasm and nucleus. Studies of related genes in other species, such as OSK1, OSK5, and OSK20, connect the SKP1 family to similar cellular processes, though these associations are not yet established in barrel medic.
