Arabidopsis	At4g35540	Plant-specific TFIIB-related protein that plays important roles in pollen germination and embryogenesis, possibly by regulating gene expression through interaction with TBP2 and the subunits of RNA polymerases.	Pollen-expressed transcription factor 2 encodes a novel plant-specific TFIIB-related protein that is required for pollen germination and embryogenesis in Arabidopsis.; 2013; DOI: 10.1093/mp/sst083; PMID: 23713077; https://pubmed.ncbi.nlm.nih.gov/23713077/
