Transcription Termination and Chimeric RNA Formation Controlled by Arabidopsis thaliana FPA
Alternative cleavage and polyadenylation influence the coding and regulatory potential of mRNAs and where transcription termination occurs. Although widespread, few regulators of this process are known. The Arabidopsis thaliana protein FPA is a rare example of a trans-acting regulator of poly(A) site choice. Analysing fpa mutants therefore provides an opportunity to reveal generic consequences ...
متن کاملThe spen family protein FPA controls alternative cleavage and polyadenylation of RNA.
The spen family protein FPA is required for flowering time control and has been implicated in RNA silencing. The mechanism by which FPA carries out these functions is unknown. We report the identification of an activity for FPA in controlling mRNA 3' end formation. We show that FPA functions redundantly with FCA, another RNA binding protein that controls flowering and RNA silencing, to control ...
متن کاملExpression analysis of the Arabidopsis thaliana AtSpen2 gene, and its relationship with other plant genes encoding Spen proteins
Proteins of the Split ends (Spen) family are characterized by an N-terminal domain, with one or more RNA recognition motifs and a SPOC domain. In Arabidopsis thaliana, the Spen protein FPA is involved in the control of flowering time as a component of an autonomous pathway independent of photoperiod. The A. thaliana genome encodes another gene for a putative Spen protein at the locus At4g12640,...
متن کاملYeast Two Hybrid cDNA Screening of Arabidopsis thaliana for SETH4 Protein Interaction
SETH4 coding sequence with 2013 bp is a member of gene family expressed in gametophytic tissues of Arabidopsis thaliana. This fragment was PCR amplified using Kod Hi Fi DNA polymerase enzyme. This fragment was cloned into pGBKT7 bate vector and transformed E. coli DH5? cells containing vector were selected on LB medium containing Kanamycin. Finally, pGBKT7-SETH4 bate was transformed into yeast ...
متن کاملExpression analysis of Arabidopsis thaliana small secreted protein genes.
Small proteins secreted to the extracellular matrix in plants regulate many physiological activities, including pathogen response, material transport, and morphogenesis, but the functions of most small secreted proteins have not been elucidated except for some well-known small secreted proteins. To predict the functions and physiological roles of unidentified small secreted proteins, informatio...
