Additional Names:
DRAM Antibody: DRAM, DRAM, DNA damage-regulated autophagy modulator protein 1, Damage-regulated autophagy modulator
Application Note:
WB: 1-2 μg/mL; IF: 20 μg/mL; IHC: 2-2.5 μg/mL.

Antibody validated: Western Blot in human mouse and rat samples; Immunofluorescence and Immunohistochemistry in human and mouse samples. All other applications and species not yet tested.
Background:
DRAM Antibody: Damage-regulated autophagy modulator (DRAM) is a p53 target gene encoding a lysosomal protein that induces autophagy, a process that degrades cytosolic proteins and organelles. It has been suggested that activation of DRAM by p53 is simultaneous to the activation by p53 of one or more proapoptotic genes such as PUMA, Bax, etc., and that the signaling pathways regulated by these genes together promote a full cell death response. By itself, DRAM cannot induce apoptosis, but the fact that it is inactivated in certain cancers highlights the importance of DRAM and suggests that autophagy may play a more important role in cancer than initially suspected. At least two different isoforms of DRAM are known to exist.

DISCLAIMER:
Optimal dilutions/concentrations should be determined by the end user. The information provided is a guideline for product use. This product is for research use only.
Immunogen:
Anti-DRAM antibody (4035) was raised against a peptide corresponding to 16 amino acids near the amino terminus of human DRAM.

The immunogen is located within amino acids 30-80 of DRAM.
ISOFORMS:
Human DRAM has 2 isoforms, including isoform 1 (238aa, 26kD) and isoform 2 (128aa, 14kD). Mouse DRAM also has 2 isoforms, including isoform 1 (238aa, 26kD) and isoform 2 (132aa, 15kD). Rat DRAM has only one isoform (238aa, 26kD). 4035 can detect both human isoforms , and also detect mouse and rat.

VALIDATION:

Independent Antibody Validation in Cell lines (Figure 2) shows similar DRAM expression profile in human, mouse and rat cell lines detected by two independent anti-DRAM antibodies that recognize different epitopes, 4033 against C-terminus domain and 4035 against N-terminus domain. DRAM proteins are detected in the most tested cell lines at different expression levels by the two independent antibodies.
