HH1 — Verticillium dahliae

Summary

VDAG_03549, also known as VdHH1, encodes a protein with ubiquitin-binding and DNA-binding activities, belonging to the TC-DDR regulator family and containing CUE and DEF1_CUE domains. In Verticillium dahliae, this gene is associated with ethylene anabolism, spore germination, and DNA repair. The encoded protein localizes to the chromosome telomeric region, cytoplasm, and nucleus. Studies of related genes in other species link the family to domains including Histone_H1/H5_H15 and vesicle transport components, though these associations are not established for VdHH1 itself. The gene is also related to NPKA and HH1.
