 5-68 2.72e-32

Cold-Shock Protein (CSP) contains an S1-like cold-shock domain (CSD) that is found in eukaryotes, prokaryotes, and archaea. CSP's include the major cold-shock proteins CspA and CspB in bacteria and the eukaryotic gene regulatory factor Y-box protein. CSP expression is up-regulated by an abrupt drop in growth temperature. CSP's are also expressed under normal condition at lower level. The function of cold-shock proteins is not fully understood. They preferentially bind poly-pyrimidine region of single-stranded RNA and DNA. CSP's are thought to bind mRNA and regulate ribosomal translation, mRNA degradation, and the rate of transcription termination. The human Y-box protein, which contains a CSD, regulates transcription and translation of genes that contain the Y-box sequence in their promoters. This specific ssDNA-binding properties of CSD are required for the binding of Y-box protein to the promoter's Y-box sequence, thereby regulating transcription.

cold shock domain protein CspD; This model represents what appears to be a phylogenetically distinct clade, containing E. coli CspD (SP|P24245) and related proteobacterial proteins within the larger family of cold shock domain proteins described by pfam00313. The gene symbol cspD may have been used idependently for other subfamilies of cold shock domain proteins, such as for B. subtilis CspD. These proteins typically are shorter than 70 amino acids. In E. coli, CspD is a stress response protein induced in stationary phase. This homodimer binds single-stranded DNA and appears to inhibit DNA replication.
