MS5 — Brassica napus

Summary

BnMS5 (MS5, TDM1) on chromosome A09 of oilseed rape encodes a protein with protein-binding activity. The gene is associated with meiotic prophase I, including leptotene and pachytene stages, as well as meiosis I, the meiotic cell cycle, male meiotic nuclear division, microsporogenesis, and pollen exine formation. It is also linked to negative regulation of translation, mitosis, and developmental processes. The encoded protein localises to the nucleus and P-bodies. Associations with heterosis, cell cycle transitions, meiotic progression, meiosis termination, gametophytic development, and meiotic division have been reported. Studies of related genes in other species link the MS5/SDI1 family, which contains TPR domains, to male fertility, meiotic exit, seed development, and genomic imprinting.
