POGZ: Lysates

Pogz is a zinc-finger protein containing at least 8 C2H2 zinc fingers, a CENP-B (centromere protein-B) domain, and a DDE domain found in the bacterial transposase/retroviral integrase family. Members of this family of integrases share structural homologies and show similar catalytic activity to the RAG1 and RAG2 proteins that initiate V(D)J recombination in lymphoid progenitors. Mouse Pogz has a human homolog with a base pair similarity of 90% and amino acid similarity of 93% for the full length protein. In humans at least 3 variants have been predicted and they are all similar at the Nterminus. A number of expressed sequence tags (ESTs) cloned from murine undifferentiated ES cells and Lin-/c-Kit+/Sca-1+ hematopoietic stem cell cDNA libraries correspond to the Pogz gene, further underlining an important function for this gene in stem cells. In mice, deletion of the gene in all tissues early in embryogenesis has been shown to be lethal.
