CPS3B_ARATH - PTM Information in dbPTM

Basic Information of Protein

• UniProt ID: CPS3B_ARATH
• UniProt AC: Q8GUU3
• Protein Name: Cleavage and polyadenylation specificity factor subunit 3-II
• Gene Name: CPSF73-II
• Organism: Arabidopsis thaliana (Mouse-ear cress).
• Sequence Length: 613
• Subcellular Localization: Nucleus .
• Protein Description: Component of the cleavage and polyadenylation specificity factor (CPSF) complex that play a key role in pre-mRNA 3'-end formation, recognizing the AAUAAA signal sequence and interacting with poly(A) polymerase and other factors to bring about cleavage and poly(A) addition. May function as mRNA 3'-end-processing endonuclease and also be involved in the histone 3'-end pre-mRNA processing..
