Function
Binding protein (BiP) is enssential in folding of secretory proteins. Bip has a function in folding seed storage proteins in the ER lumen. OsBip1 reported by Park and his colleagues and BiP3 reported by Wakasa,Yasuda,et al are the same gene. In rice overpressing BiP1 , XA21-mediated immunity is compromised, XA21 stability is significantly decreased, and XA21 proteolytic cleavage is inhibited. Meanwhile,Wakasa,Yasuda, et al believe that severe suppression (BiP1 KD) or significant over-expression (BiP1 OEmax) of BiP1 can alter seed phenotype and the intracellular structure of endosperm cells and reduce seed storage protein content, starch accumulation and grain weight.
Expression
1. Researchers conclude that the peptides from the 140 kDa proteins can match XA21 from the N-terminal LRR region to the C-terminal kinase domain.However,the peptides from the 110 kDa protein match the LRR, but not the kinase domain. 2.Gene BiP3,predicted to encode a 666 amino acid protein with a molecular mass of 73.4 kDa ,has a 1,998 bp open reading frame which consists of 7 introns and 8 exons.In overall structure,BiP3 is similar to other known HSP70s in plants and animals.It has an approximately 45 kDa domain at the N-terminus that is predicted to have ATPase activity and a domain of approximately 25 kDa at the C-terminus having a predicted substrate-binding domain.
Evolution
1.BiP is one of the major ER chaperones and belongs to the heat shock protein 70 (HSP70) family.Rice BiP3 (OsBiP3) shows the greatest similarity to ArabidopsisBiP1 and BiP2 with 89.2% and 89.3% identity. 2.BiP with an ATPase domain at its N-terminus and a protein-binding domain at its C-terminus allows BiP to cycle between ATP hydrolysis and ADP exchange, and it is coupled to binding and release of the unfolded protein. 3.BiP protein has a KDEL ER retention signal at the C-terminus and is retained in the ER lumen. BiP interacts with nascent immature secretory proteins synthesized from membrane-bound polysomes on the ER,and assists in protein folding in concert with other chaperones and folding helpers such as calnexin and protein disulfide isomerase-like proteins in the ER lumen. BiP not only participates in assistence of protein folding but also take part in the protein degradation process known as ER-associated degradation. 4.Scientists reported that over-expression of BiP1 (Os02g0115900) in transgenic rice seed resulted in an opaque phenotype and abnormal intracellular structure.
