NCBP1_ARATH - PTM Information in dbPTM

Basic Information of Protein

Overview of Protein Modification Sites with Functional and Structural Information
UniProt ID	NCBP1_ARATH
UniProt AC	Q9SIU2
Protein Name	Nuclear cap-binding protein subunit 1
Gene Name	ABH1
Organism	Arabidopsis thaliana (Mouse-ear cress).
Sequence Length	848
Subcellular Localization	Nucleus . Cytoplasm . Predominantly nuclear.
Protein Description	Component of the cap-binding complex (CBC), which binds cotranscriptionally to the 5'-cap of pre-mRNAs and is involved in various processes such as pre-mRNA splicing and RNA-mediated gene silencing (RNAi) by microRNAs (miRNAs). The CBC complex is involved in miRNA-mediated RNA interference and is required for primary miRNA processing. In the CBC complex, ABH1/CBP80 does not bind directly capped RNAs (m7GpppG-capped RNA) but is required to stabilize the movement of the N-terminal loop of CBP20 and lock the CBC into a high affinity cap-binding state with the cap structure. Involved in flowering regulation, possibly by regulating pre-mRNA splicing of FLC gene. Acts as a negative regulator of abscisic acid signaling in guard cells..
