Gene : AT2G42940 A. thaliana

DB identifier	AT2G42940	Secondary Identifier	locus:2045585
Brief Description	Putative AT-hook DNA-binding family protein

TAIR Computational Description	Putative AT-hook DNA-binding family protein;(source:Araport11)
TAIR Curator Summary	Encodes a nuclear matrix protein with AT-hook DNA binding motifs that acts in the maintenance of genomic integrity by silencing TEs and repeat-containing genes through epigenetic machinery. It interacts with FVE and MSI5 which are components of HDAC corepressor complexes. It is expressed in tapetum during the tetrad stage.

Type	Comment	Proteins
AHL16_ARATH	developmental stage	Expressed in tapetum during the tetrad stage.
AHL16_ARATH	function	Transcription factor that specifically binds AT-rich DNA sequences related to the nuclear matrix attachment regions (MARs) (PubMed:25336567). Encodes a nuclear matrix protein that acts in the maintenance of genomic integrity by silencing TEs and repeat-containing genes through epigenetic machinery. Acts as a chromatin remodeling factor that modifies the architecture of FLC and FWA chromatin by modulating both H3 acetylation and methylation leading to the regulation of FLC and FWA expression (PubMed:23394836, PubMed:23836195). Negatively regulates floral repressors including MAF4 and MAF5 (PubMed:23733063). Plays a transcription activation role in anther development. Regulates the expression of arabinogalactan proteins (AGPs) involved in the formation of the nexine layer of the pollen wall (PubMed:24804694, PubMed:25336567). Binds AGP6, AGP11, AGP23 and AGP40 promoters (PubMed:25336567).
AHL16_ARATH	tissue specificity	Preferentially expressed in the inflorescence meristem and young floral buds, as well as in seedling-stage vegetative meristems (PubMed:23394836). Widely expressed in flowers, roots and stems, with relatively low expression in leaves (PubMed:24804694).
