RBF1 — Verticillium dahliae

Summary

VdRBF1 (VDAG_04356) in Verticillium dahliae encodes a replication initiator 1 protein with transcription coactivator activity. The gene is associated with melanin anabolism, chromatin modeling, and positive regulation of transcription by RNA polymerase II, and its product localizes to the nucleus. VdRBF1 is also linked to the related genes SPT20, ADN2, and SOM1 (centered on VTA2). Studies of related genes in other species, including Verticillium nonalfalfae and various Fusarium species, connect the family to the Spt20-like_SEP domain and autophagy-related protein 27, though these associations are not established for VdRBF1 itself.
