Function

As a component of the LINC (LInker of Nucleoskeleton and Cytoskeleton) complex, involved in the connection between the nuclear lamina and the cytoskeleton. The nucleocytoplasmic interactions established by the LINC complex play an important role in the transmission of mechanical forces across the nuclear envelope and in nuclear movement and positioning. Specifically, SYNE2 and SUN2 assemble in arrays of transmembrane actin-associated nuclear (TAN) lines which are bound to F-actin cables and couple the nucleus to retrograde actin flow during actin-dependent nuclear movement. Required for interkinetic nuclear migration (INM) and essential for nucleokinesis and centrosome-nucleus coupling during radial neuronal migration in the cerebral cortex and during glial migration. Required for nuclear migration in retinal photoreceptor progenitors implicating association with cytoplasmic dynein-dynactin and kinesin motor complexes, and probably B-type lamins; SUN1 and SUN2 seem to act redundantly. The SUN1/2:KASH5 LINC complex couples telomeres to microtubules during meiosis; SUN1 and SUN2 seem to act at least partial redundantly. Anchors chromosome movement in the prophase of meiosis and is involved in selective gene expression of coding and non-coding RNAs needed for gametogenesis. Required for telomere attachment to nuclear envelope and gametogenesis. May also function on endocytic vesicles as a receptor for RAB5-GDP and participate in the activation of RAB5.

Activity summary

SUN2 also known as Sad1 and UNC84 domain containing 2 is a protein that plays a fundamental role in the positioning of the nucleus in cells. It has a mass of approximately 89 kDa. This protein localizes to the inner nuclear membrane where it is involved in tethering the nucleus to the cytoskeleton. SUN2 is mainly expressed in tissues exhibiting high mechanical stress such as muscle and bone tissue. Its structural role anchors the nuclear lamina to the cytoskeleton helping to maintain cellular integrity.

Biological function summary

SUN2 connects the nuclear interior with the cytoskeleton through the LINC complex (Linker of Nucleoskeleton and Cytoskeleton). This complex also includes other proteins like Nesprin and Lamins helping to transmit mechanical signals across the nuclear envelope. SUN2 plays an essential role in processes like cell division nuclear migration and chromosomal positioning. Its function in the LINC complex makes it a significant player in maintaining nuclear morphology and ensuring proper cell division.

Pathways

SUN2 is involved in the mechanotransduction and cell-cycle regulation pathways. In mechanotransduction SUN2 helps translate mechanical signals into biochemical ones therefore influencing gene expression. Related proteins like Nesprin-2 interact within the LINC complex and contribute to these pathways. In cell-cycle regulation the protein helps align the mitotic spindle through connection with components of the cytoskeleton supporting accurate cell division. These pathways demonstrate SUN2's contribution to cellular responses to mechanical stimuli and cell growth regulation.

Associated diseases and disorders

Studies indicate that SUN2 mutations or abnormal expression levels are associated with muscular dystrophy and cancer. In muscular dystrophy defects in SUN2 can lead to impaired nuclear anchoring contributing to muscle weakness. It interacts with Lamin A/C and defects in these proteins are also linked to muscular dystrophies. In cancer SUN2 dysregulation may affect cellular architecture and chromosomal stability contributing to tumorigenesis. Understanding SUN2's roles and interactions offers potential pathways for therapeutic interventions.
