Descrição geral

Ceramide kinase (CERK) is a 537-amino acid protein. It has a catalytic region, a putative amino-myristoylation site in its amino terminal region and a pleckstrin homology domain. The gene encoding CERK is localized on human chromosome 22q13.31.
Human ceramide kinase (CERK) (GenBank Accession No. NM_022766), 1-537 (end) with C-terminal Flag-tag, MW= 60 kDa, expressed in Baculovirus expression system.

Aplicação

Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.

Ações bioquímicas/fisiológicas

Ceramide kinase (CERK) is an enzyme involved in sphingolipid metabolism and in the synthesis of ceramide-1-phosphate. It associates with calmodulin and at the time of Fc receptor-mediated phagocytosis, it aggregates in lipid rafts. CERK may have a role in calcium signaling. The protein functions in the phagocytosis of polymorphonuclear leukocytes and degranulation of mast cells.

Definição da unidade

One unit is defined as the amount of enzyme required to produce 1 pmole of ceramide-1-phosphate/min at 37°C.

Ceramide kinase (CERK) converts ceramide to ceramide-1-phosphate (C1P), which has recently emerged as a new bioactive molecule capable of regulating diverse cellular functions. The N-terminus of the CERK protein encompasses a sequence motif known as a pleckstrin homology (PH) domain.

Ceramide kinase (CerK) has important roles in leukocyte functions, including the role in degranulation of mast cells and the phagocytosis of polymorphonuclear leukocytes, so its expression levels should be strictly regulated. Here, we report that the mRNA expression and enzyme
