SKP1 — Medicago truncatula

Summary

MTR_4G032510 (SKP1) in barrel medic (Medicago truncatula) on chromosome 4 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, specifically SCF-dependent proteasomal ubiquitin-dependent protein breakdown, as well as cell cycle, cell division, cell motility, secretion, and homeostasis. It is linked to jasmonic acid (JA) signaling, leaf development, flower development, and organ growth. The encoded product localizes to both the cytoplasm and nucleus. Associations with leaf size have also been noted. Studies of related genes in other species connect the SKP1 family to similar cellular processes, though these findings are not yet established for this specific gene.
