NRPD4_ARATH - PTM Information in dbPTM

Basic Information of Protein

Overview of Protein Modification Sites with Functional and Structural Information
UniProt ID	NRPD4_ARATH
UniProt AC	Q6DBA5
Protein Name	DNA-directed RNA polymerases IV and V subunit 4
Gene Name	NRPD4
Organism	Arabidopsis thaliana (Mouse-ear cress).
Sequence Length	205
Subcellular Localization	Nucleus . Detected as small foci dispersed throughout the nucleoplasm.
Protein Description	DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Component of RNA polymerases IV and V which mediate short-interfering RNAs (siRNA) accumulation and subsequent RNA-directed DNA methylation-dependent (RdDM) transcriptional gene silencing (TGS) of endogenous repeated sequences, including transposable elements. Required for the de novo DNA methylation directed by the RdDM pathway..
