PABN3_ARATH - PTM Information in dbPTM

Basic Information of Protein

Overview of Protein Modification Sites with Functional and Structural Information
UniProt ID	PABN3_ARATH
UniProt AC	Q9LX90
Protein Name	Polyadenylate-binding protein 3 {ECO:0000303\|PubMed:18479511}
Gene Name	PABN3 {ECO:0000303\|PubMed:18479511}
Organism	Arabidopsis thaliana (Mouse-ear cress).
Sequence Length	217
Subcellular Localization	Nucleus speckle . Cytoplasm . Shuttles between the nucleus and the cytoplasm but predominantly found in the nucleus.
Protein Description	Involved in the 3'-end formation of mRNA precursors (pre-mRNA) by the addition of a poly(A) tail of 200-250 nt to the upstream cleavage product. Stimulates poly(A) polymerase (PAPOLA) conferring processivity on the poly(A) tail elongation reaction and controls also the poly(A) tail length. Increases the affinity of poly(A) polymerase for RNA. Binds to poly(A) and to poly(G) with high affinity. May protect the poly(A) tail from degradation..
