Gene Information

human ... IMPACT(55364)

General description

Protein IMPACT (UniProt Q9P2X3; also known as Imprinted and ancient gene protein homolog) is encoded by the IMPACT gene (Gene ID 55364) in human. IMPACT is a cytoplasmic protein preferentially expressed in neurons. IMPACT is highly abundant in the hypothalamus and in scattered neurons in other areas, such as the hippocampal interneurons. IMPACT and its yeast ortholog Yih1 contain an RWD domain (a.a. 14-116 of human and mouse IMPACT) that interacts with GCN1 and competes against GCN2 for GCN1 binding. IMPACT and Yih1 overexpression in mouse embryonic fibroblasts (MEFs) and yeasts inhibits GCN2 activation induction. IMPACT is a developmentally regulated protein that promotes neuritogenesis, while GCN2 strongly inhibits spontaneous neurite outgrowth. Increased abundance of IMPACT in differentiated neuronal cells enhances translation initiation by preventing GCN2 signaling.

Specificity

This polyclonal antibody was raised against the C-terminal end sequence present in both spliced isoforms of human IMPACT reported by UniProt (Q9P2X3).

Immunogen

Epitope: C-terminus
KLH-conjugated linear peptide corresponding to the C-terminal sequence of human IMPACT.

Application

Anti-IMPACT Antibody, Cat. No. ABN1444, is a highly specific rabbit polyclonal antibody that targets IMPACT and has been tested in Immunohistochemistry and Western Blotting.
Immunohistochemistry Analysis: A 1:250 dilution from a representative lot detected IMPACT in human prostate cancer, as well as in normal human cerebral cortex and mouse cerebellum tissue sections.
Research Category
