FunctionRate limiting enzyme in the de novo synthesis of guanine nucleotides and therefore is involved in the regulation of cell growth. It may also have a role in the development of malignancy and the growth progression of some tumors.
Tissue specificityIMP type I is the main species in normal leukocytes and type II predominates over type I in the tumor.
PathwayPurine metabolism; XMP biosynthesis via de novo pathway; XMP from IMP: step 1/1.
Sequence similaritiesBelongs to the IMPDH/GMPR family.
Contains 2 CBS domains.
modificationsThe N-terminus is blocked.

ab131158 staining IMPDH2 in K562 (human chronic myelogenous leukemia) cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with 4% PFA and permeabilized with 0.1% triton X-100. Samples were incubated with primary antibody at a dilution of 1/500. A goat anti rabbit IgG (Alexa Fluor® 488) (ab150077) was used as the secondary antibody at a dilution of 1/1000.
DAPI was used as a nuclear counterstain and the negative control was PBS only.
