Description

BAK1 (Bcl-2 homologous antagonist/killer) is a crucial protein involved in regulating apoptosis, or programmed cell death, which is essential for maintaining cellular homeostasis. It functions as a pro-apoptotic factor, promoting cell death in response to various stress signals. BAK1 belongs to the BCL-2 family of proteins and plays a crucial role in the mitochondrial apoptotic process by promoting mitochondrial outer membrane permeabilization, which leads to the release of apoptogenic factors into the cytosol. BAK1 is regulated through interactions with other proteins, such as BCL-2 family members, which can either inhibit or promote its apoptotic activity. Dysregulation of BAK1 has been implicated in several diseases, thus, overexpression of BAK1 can contribute to neurodegenerative and autoimmune diseases by promoting excessive cell death. Conversely, inhibition of BAK1 is associated with the development of cancers, as it allows cells to evade apoptosis and continue proliferating.

Antigen Details

Structure: BAK1 protein consists of 211 amino acids with a predicted molecular weight of 23 kDa.
Distribution: Mitochondrial outer membrane
Function: • Pro-apoptotic role: BAK1 promotes apoptosis by facilitating mitochondrial outer membrane permeabilization.
• Interaction with BCL-2 family: It interacts with other BCL-2 family proteins to regulate apoptosis.
• Release of apoptogenic factors: Upon activation, BAK1 helps release factors from the mitochondria that trigger the apoptotic cascade.
Interaction: • BCL-2 and BCL-XL: These anti-apoptotic proteins bind to BAK1, inhibiting its pro-apoptotic activity.
• BAX: BAK1 forms heterooligomers with BAX, another pro-apoptotic protein, to promote mitochondrial outer membrane permeabilization.
• p53: The tumor suppressor protein p53 interacts with BAK1 in response to cellular stress, enhancing its apoptotic function.
• MCL1: This anti-apoptotic protein also interacts with BAK1, regulating its activity.
• VDAC2: BAK1 interacts with the mitochondrial voltage-dependent anion channel 2, which is involved in the release of apoptogenic factors
Biology Area: Apoptosis/Tumor Suppressors/Cell Death, Cancer Biomarkers, Cell Biology, Mitochondrial Function, Neurodegeneration
Molecular Family: Mitochondrial Markers

Regulation: • Protein interactions: BAK1 is regulated through its interactions with pro- and anti-apoptotic BCL-2 family members.
• Activation by stress signals: It remains inactive until activated by various cellular stress signals.
• Post-translational modifications: Phosphorylation and other modifications can influence BAK1's activity and stability.
