General annotation (Comments)

Function

Involved in the regulation of cell growth. May stabilize the active CDC2-cyclin B1 complex and thereby contribute to the regulation of the cell cycle and the prevention of uncontrolled cell proliferation. May act as a tumor suppressor. Ref.1 Ref.4 Ref.5

Subunit structure

Binds EEF1G, TLK2 and CDK1.

Subcellular location

Cytoplasm By similarity. Cell membrane By similarity. Cell projectiondendritic spine By similarity. Cell junctionsynapsepostsynaptic cell membranepostsynaptic density By similarity. Cell junctionsynapse By similarity. Note: Associated with the plasma membrane and with microtubules. Detected in dendritic spines, especially in the postsynaptic density By similarity. Ref.5

Tissue specificity

Highly expressed in testis, prostate, spleen, thymus, ovary and brain. Detected at lower levels in heart, placenta, small intestine, colon, liver, kidney, skeletal muscle and pancreas. Not detectable in primary tumors from breast and prostate and in many cancer cell lines. Ref.1

Post-translational modification

Phorphorylated on serine residues. Hyperphosphorylated by the cAMP-dependent kinase PKA during cell-cycle progression. Ref.5

Involvement in disease

Defects in LZTS1 may be a cause of esophageal cancer (ESCR) [MIM:133239]. A malignancy of the esophagus. The most common types are esophageal squamous cell carcinoma and adenocarcinoma. Cancer of the esophagus remains a devastating disease because it is usually not detected until it has progressed to an advanced incurable stage. Ref.1

Miscellaneous

Defects in LZTS1 are found in many types of tumors.

Sequence similarities

Belongs to the LZTS family.
