AP1 — Medicago truncatula

Summary

MTR_2G085280 (symbol AP1) on barrel medic chromosome 2 encodes a protein with a MADS-box domain and a MEF2-like N-terminal domain. The protein localises to the nucleus and exhibits RNA polymerase II transcription regulatory region sequence-specific DNA binding, protein dimerization activity, and DNA-binding transcription factor activity. AP1 is associated with flower development, inflorescence development, carpel development, seed development, cell differentiation, and regulation of transcription by RNA polymerase II. It has also been connected to inflorescence branching and meristem identity. Related genes in other species link the family to floral organ specification and meristem determinacy, though these functions are not yet established for this specific gene.
