Antibody Quality and Performance Guarantee
| Rabbit anti HRK antibody detects Harakiri (HRK), also known as Neuronal death protein DP5 or BH3-interacting domain-containing protein 3. HRK is a BH3 only protein of the Bcl-2 family, which promotes Bax dependent apoptosis. HRK regulates apoptosis through its interaction with the anti-apoptotic proteins Bcl-2 and Bcl-XL, and in conjunction to the mitochondrial pore forming protein p32. HRK is thought to have a specific role in initiating neuronal and haematopoietic cell apoptosis, in particular to growth factor deprivation. Aberrant methylation of HRK is frequently detected in primary colorectal cancers. Despite its predicted molecular weight of ~18 kDa, HRK often migrates at ~12-15 kDa. |
