SKP1 — Medicago truncatula

Summary

MTR_4G021390, the SKP1 gene of barrel medic (Medicago truncatula) on chromosome 4, encodes a member of the SKP1 protein family, which includes the SKP1-like dimerisation and POZ domains and is characterised by cullin family protein binding activity. This gene is associated with protein ubiquitination, particularly SCF-dependent proteasomal ubiquitin-dependent protein breakdown, as well as cell cycle, cell division, cell motility, secretion, and homeostasis. It has been linked to jasmonic acid (JA) signalling, leaf development, flower development, and organ growth, and is associated with leaf size. The encoded protein localises to both the cytoplasm and nucleus. Studies of related genes in other species further connect the SKP1 family to these processes.
