Activity summary

SEPT5 also known as PNUTL1 or hCNTRL is a protein involved in the mechanics of cellular division and membrane dynamics. It has a molecular mass of about 39 kDa and is predominantly found in neuronal and hematopoietic tissues. SEPT5 functions as part of the septin family which plays a role in cytoskeletal rearrangements. Within cells SEPT5 assembles into filaments essential for maintaining structural integrity during cell division.

Biological function summary

SEPT5 is involved in bundling and organizing actin filaments. It forms part of a larger septin complex which includes other septin proteins like SEPT2 and SEPT7. This complex is responsible for the proper organization and stability of cytoskeletal structures which is important for processes like cytokinesis and exocytosis. SEPT5's ability to bind lipid membranes indicates its role in membrane-trafficking processes. Its interactions with vesicular proteins suggest SEPT5's involvement in neurotransmitter release.

Pathways

SEPT5 plays a role in the cell cycle and synaptic vesicle trafficking pathways. In the cell cycle SEPT5 collaborates with proteins such as Cdc42 and calmodulin to ensure accurate division timing and fidelity. In synaptic vesicle trafficking SEPT5 associates with proteins like syntaxin and SNARE complexes contributing to the regulation of neurotransmitter release. These pathways highlight the importance of SEPT5 in both cell proliferation and nervous system functioning.

Associated diseases and disorders

SEPT5 has been implicated in conditions like Parkinson's disease and acute myeloid leukemia (AML). In Parkinson's disease SEPT5 may interact with alpha-synuclein which is known to disrupt synaptic function and contribute to the pathogenesis of the disorder. In AML deregulation of SEPT5 expression disturbs normal cell division processes. Its interactions with other septins and cell cycle regulators have implications for understanding its role in these diseases.
