Background Information
SEPT2 belongs to a family of septins, GTP-binding proteins that are a component of the cytoskeleton. Septins can assemble into intracellular structures of various shapes and are known to influence membrane stability, forming diffusion barriers and serving as scaffolds.
What is the molecular weight of SEPT2? Is SEPT2 post-translationally modified?
The molecular weight of SEPT2 is 45 kDa. In a cellular context, SEPT2 forms hetero-hexamers and hetero-octamers with other septins. These hexamers and octamers further assemble into high-order structures such as filaments and rings. SEPT2 can be phosphorylated on Ser218 by casein kinase 2 (PMID: 19165576) and can also be SUMOylated (PMID: 29051266).
What is the subcellular localization of SEPT2?
SEPT2 forms a diffusion barrier and localizes to the primary cilium; in some cell types, it has been found at the transition zone/basal body (PMID: 20558667), while in others localized to the axoneme (PMID: 23572511). During cell division, SEPT2 accumulates near the contractile ring from anaphase through telophase, and finally condenses into the midbody (PMID: 9203580). In interphase cells, SEPT2 was found to associate with polyglutamylated microtubules (PMID: 18209106) and can affect microtubule dynamics via interaction with MAP4.
What is the tissue expression pattern of SEPT2?
While some septins have tissue-specific expression profiles, SEPT2 is ubiquitously expressed (PMID: 22314400).

Reviews
The reviews below have been submitted by verified Proteintech customers who received an incentive forproviding their feedback.
FH Christine (Verified Customer) (01-27-2023) | Incubation for a few hours at room temperature on HEK293T lysates. Detection of a very strong signal just below the 47 kDa marker (expected size of Septin 2) and a fainter signal just above the 47 kDa marker.
|
FH Mohammed (Verified Customer) (08-19-2020) | Some staining at the annulus, there seems to be staining in the acrosome. Overall, really high background (even when the concentration is lowered).
