Plays a role in the control of vascular smooth muscle (VSM) alpha-actin gene transcription as repressor in myoblasts and fibroblasts. Participates in transcriptional and translational regulation of alpha-MHC expression in cardiac myocytes by binding to the purine- rich negative regulatory (PNR) element. Modulates constitutive liver galectin-3 gene transcription by binding to its promoter. May play a role in the dendritic transport of a subset of mRNAs (By similarity). {ECO:0000250, ECO:0000269|PubMed:1448097}. |PurA| |purine-rich negative regulatory element binding| |DNA replication factor A complex| |SMAD binding| |double-stranded DNA binding| |single-stranded DNA binding| |mRNA binding| |regulation of myeloid cell differentiation| |DNA-binding transcription repressor activity, RNA polymerase II-specific| |RNA polymerase II regulatory region sequence-specific DNA binding| |transcription factor binding| |sequence-specific DNA binding| |regulation of hemopoiesis| |cell population proliferation| |negative regulation of transcription by RNA polymerase II| |negative regulation of transcription, DNA-templated| |negative regulation of nucleic acid-templated transcription| |negative regulation of RNA biosynthetic process| |negative regulation of RNA metabolic process| |negative regulation of cellular macromolecule biosynthetic process| |RNA binding| |negative regulation of nucleobase-containing compound metabolic process| |negative regulation of macromolecule biosynthetic process| |negative regulation of cellular biosynthetic process| |negative regulation of biosynthetic process| |DNA-binding transcription factor activity, RNA polymerase II-specific| |regulation of immune system process| |negative regulation of gene expression| |regulation of cell differentiation| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp81|Selumetinib 20μM R02 exp81]]|-1.78| |[[:results:exp93|DABN racemic mixture R03 exp93]]|2.24| No correlation found to any other genes in chemogenomics.
