SKP1 — Medicago truncatula

Summary

MTR_7G094410, the SKP1 gene of barrel medic (Medicago truncatula) on chromosome 7, encodes a member of the SKP1-like protein family. The encoded protein possesses cullin family protein binding activity and is associated with protein ubiquitination and SCF-dependent proteasomal ubiquitin-dependent protein breakdown. It is linked to cell cycle, cell division, cell motility, secretion, and homeostasis, as well as to jasmonic acid signaling, leaf development, flower development, and organ growth. The protein localises to both the cytoplasm and the nucleus. Additionally, this gene is associated with leaf size. Studies of related genes in other species, such as OSK1, OSK5, and OSK20, further support the family's role in ubiquitination pathways.
