Disease relevance of WCSP1
- A wheat cDNA encoding a putative nucleic acid-binding protein, WCSP1, was isolated and found to be homologous to the predominant CspA of Escherichia coli [1].
- WCSP1 induction was cold-specific because neither abscisic acid treatment, drought, salinity, nor heat stress induced WCSP1 expression [1].
High impact information on WCSP1
- Structural and expression similarities to E. coli CspA suggest that WCSP1 may be involved in gene regulation during cold acclimation [1].
- The putative WCSP1 protein contains a three-domain structure consisting of an N-terminal cold shock domain with two internal conserved consensus RNA binding domains and an internal glycine-rich region, which is interspersed with three C-terminal CX(2)CX(4)HX(4)C (CCHC) zinc fingers [1].
Analytical, diagnostic and therapeutic context of WCSP1
- Northern and Western blot analyses showed that WCSP1 mRNA and protein levels steadily increased during cold acclimation, respectively [1].
