MTLA1 — Candida albicans

Summary

C5_01740C_A (MTLA1) in Candida albicans chromosome 5 encodes a homeodomain (HD) protein with DNA-binding transcription factor activity, specifically RNA polymerase II-specific. As a nuclear-localized regulator, MTLA1 is associated with mating, sexual reproduction, and karyogamy, as well as the regulation of phenotypic switching, chlamydospore formation, and biofilm formation. It has been linked to hyphal growth, filamentous growth, and cell growth, alongside processes such as sporulation, meiosis, and the glyoxylate cycle. The gene is also associated with signal transduction, nuclear movement, and negative regulation of transcription by RNA polymerase II. Studies of the related MATA1 protein in other species, based on sequence similarity, further connect this family to mating-type regulation, though this is not directly established for C. albicans.
