Activity summary

The protein 'APPBP1' also known as APP-binding protein 1 functions as part of cellular processes through its role in protein modification. APPBP1 forms a dimeric complex with Uba3 together activating NEDD8 which is a small ubiquitin-like modifier. This protein has a molecular weight of approximately 58 kDa and is widely expressed across various tissues including the brain and liver. Its comprehensive roles make it essential for normal cellular operations.

Biological function summary

APPBP1 interacts within a complex known as the NEDD8-activating enzyme. This complex is essential in the neddylation pathway influencing protein degradation through the ubiquitin-proteasome system. By conjugating NEDD8 to target proteins APPBP1 controls many processes such as cell cycle regulation signal transduction and transcription. It is of special interest in research involving cellular signaling because neddylation modifies the activity and stability of many substrate proteins involved in these critical cellular functions.

Pathways

The involvement of APPBP1 in ubiquitin-like protein pathways highlights its influence on cellular homeostasis. The protein is associated with the neddylation and ubiquitination pathways influencing other members such as cullin proteins involved in cell cycle control and other cellular processes. APPBP1-related interactions play a significant role in ensuring the timely degradation of specific proteins maintaining balance within the cell's regulatory mechanisms.

Associated diseases and disorders

Abnormalities in APPBP1 activity have been linked to neurodegenerative diseases such as Alzheimer's disease and cancer. In Alzheimer's disease APPBP1 is related to the APP protein and altered neddylation might contribute to disease pathology through dysfunctional protein degradation pathways. In cancer disrupted neddylation can result in uncontrolled cell proliferation due to improper regulation of cell cycle pathways. Understanding the function of APPBP1 could provide insights into developing therapeutic strategies for these conditions.
