PCF4 — Arabidopsis thaliana

Summary

AT3G15030 (TCP4, also known as PCF4) encodes a TCP family transcription factor on chromosome 3 of Arabidopsis thaliana. The product possesses DNA-binding transcription activator activity and is associated with sequence-specific DNA binding, chromatin binding, and transcription coactivator activity. TCP4 has been linked to cell proliferation, leaf area, petal size and shape, and seed oil content and accumulation. It is associated with upregulation of flavonol biosynthetic process, regulation of miRNA processing, sucrose mediated signaling, and specification of symmetry. The protein localizes to the nucleus, plastid, cytosol, and cytoplasm. Associations include leaf flexibility, specific leaf weight, plastochron, harvest index, oleic acid content, seed set percent, and lignin biosynthesis trait. Studies of related genes in other species link the family to fruit shelf life, tuberization, and flavonoid metabolism.
