Activity summary

The protein SAE1 also known as SUMO-activating enzyme subunit 1 functions mechanically as a part of the SUMOylation process. It has a mass of approximately 39 kDa and is expressed in multiple cell types but is mainly found in the nucleus. SAE1 forms a heterodimeric structure with the protein SAE2 and together they are responsible for the initial step of SUMO activation which is important for SUMOylation a post-translational modification process.

Biological function summary

SAE1 is integral to numerous cellular processes that require precise regulation such as transcription DNA repair and signal transduction. It functions as part of the SUMO E1 enzyme complex which is essential for conjugating SUMO proteins to target substrates. This modification influences protein stability localization and interaction adding a layer of control in these cellular activities. The modulation of protein function by SAE1 impacts cell cycle control and stress responses indicating its breadth of influence across cellular mechanisms.

Pathways

The actions of SAE1 significantly impact the PI3K-Akt and DNA damage repair pathways. Its involvement in these pathways highlights its role in regulating cell survival and maintaining genomic integrity. SAE1's interaction within the SUMOylation machinery connects it to other proteins such as Ubc9 the E2 conjugating enzyme which highlights its importance in facilitating modifications necessary for a wide array of cellular functions and signaling cascades.

Associated diseases and disorders

Defects or dysregulation of SAE1 have been linked to cancer and neurodegenerative conditions. Altered SUMOylation levels controlled by SAE1 can influence tumorigenesis through abnormal cell proliferation or impaired DNA damage responses connecting it with proteins like p53 and PARP1 which are critical in those pathways. Additionally SAE1's involvement in neurological disorders is associated with disrupted protein homeostasis linking it to pathologies where proper cellular regulatory mechanisms are compromised.
