Histone acetylation is an important post-translational modification in eukaryotes and is regulated by two antagonistic enzymes, namely histone acetyltransferase (HAT) and histone deacetylase (HDAC). However, little has been done on the HAT superfamily in Brachypodium distachyon (B. distachyon), a new model plant of Poaceae. In this study, eight HATs were identified from B. distachyon and classified into four major families. Subcellular localization analysis showed that a majority of BdHATs were predominantly localized in the nucleus. Syntenic and phylogenetic analysis indicated there may be two common ancestral CREB-binding protein (p300/CBP, HAC) genes prior to the separation of monocots and dicots. Expression analysis revealed that the potential roles of BdHATs in B. distachyon development and responses to four abiotic stresses. Protein-protein network analysis identified some potential interactive genes with BdHATs. Thus, our results will provide solid basis for further study the function of HAT genes in B. distachyon and other monocot plants.

Service providing functional analysis of proteins by classifying them into families and predicting domains and important sites. They combine protein signatures from a number of member databases into a single searchable resource, capitalizing on their individual strengths to produce a powerful integrated database and diagnostic tool. This integrated database of predictive protein signatures is used for the classification and automatic annotation of proteins and genomes. InterPro classifies sequences at superfamily, family and subfamily levels, predicting the occurrence of functional domains, repeats and important sites. InterPro adds in-depth annotation, including GO terms, to the protein signatures. You can access the data programmatically, via Web Services. The member databases use a number of approaches: # ProDom: provider of sequence-clusters built from UniProtKB using PSI-BLAST. # PROSITE patterns: provider of simple regular expressions. # PROSITE and HAMAP profiles: provide sequence matrices. # PRINTS provider of fingerprints, which are groups of aligned, un-weighted Position Specific Sequence Matrices (PSSMs). # PANTHER, PIRSF, Pfam, SMART, TIGRFAMs, Gene3D and SUPERFAMILY: are providers of hidden Markov models (HMMs). Your contributions are welcome. You are encouraged to use the ''''Add your annotation'''' button on InterPro entry pages to suggest updated or improved annotation for individual InterPro entries.
