MEO — Nicotiana attenuata

Summary

A4A49_16528 (MEO, SKP1B) encodes a SKP1-like protein that contains Skp1 dimerisation and POZ domains and binds cullin family proteins. In coyote tobacco, this gene is associated with protein ubiquitination, ubiquitin-dependent proteolysis, and SCF-dependent proteasomal protein breakdown. It has been linked to defense responses, immune response, JA signaling, cell death, and virus-induced PTGS. Associations also include seed germination, germination rate, photosynthetic rate, plant height, and salt tolerance (SALTTL). The protein localises to both the cytoplasm and nucleus. Studies of related genes in other species link the SKP1 family to SCF complex function, though this is not established for the coyote tobacco gene.
