Chemokines are small secreted proteins functionally involved in the immune system's regulation of lymphocyte migration across numerous mammalian species. Given its growing popularity in immunological models, we investigated the structure and function of chemokine CXCL12 protein in tree shrews. We found that CXCL12 and its receptor CXCR4 in tree shrew had(More)
The mitochondrial transcription termination factor (MTERF) family is a group of highly conserved DNA-binding proteins composed of four key members, MTERF1-4. To date, several studies have investigated the binding sites of MTERF1 on mitochondrial genome and the regulation of mitochondrial gene transcription, but the more intricate connection between(More)
An extracellular cold-adapted alkaline lipase from the psychrotrophic Yersinia enterocolitica strain KM1 was purified 26-fold to homogeneity. The enzyme was active over a broad range spanning 0-60 °C with an optimum activity at 37 °C, and it was found to be alkaline-preferring with an optimum activity at pH 9.0. The molecular weight was estimated to be 34.3(More)
