Involvement of the gene ZmHLB in transport hormones in the phloem
RBPs - RNA-binding proteins are involved in different aspect of post-transcriptional gene regulation. The Puf in S. cerevisiae are structurally related family of cytoplasmatic RBPs. The proteins got several consecutive repeats of the Pumilio homology domain (Pum-HD). Bind to the 3'UTR sequence. The five members bear 6-8 Puf (Pum-HD) repeats.
Your mission, should you choose to accept it, involves identify specific mRNAs that interact with the five members of the Puf family. Finding if there is a consensus sequence in the mRNAs that binds by those Puf members.
To summarise what we already know:
TAP-tag the Puf family
Based on the Rigaut et al. 1999 - built a 5 contracts with a sequence encoding two IgG-binding units of protein A, a speciﬁc protease recognition site, and a calmodulin-binding domain, was fused in-frame at the C-terminus of the respective open reading frame (ORF)in its original chromosomal location.
Isolate Puf Proteins
