Protein attributes
| Sequence length | 596 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at protein level. |
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.3 Ref.4 |
| Subunit structure | Binds EEF1G and CDC2. |
| Subcellular location | Cytoplasm By similarity. Cell membrane By similarity. Cell projection › dendritic spine By similarity. Cell junction › synapse › postsynaptic cell membrane › postsynaptic density By similarity. Cell junction › synapse By similarity. Note: Associated with the plasma membrane and with microtubules. Detected in dendritic spines, especially in the postsynaptic density By similarity. Ref.4 |
| 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.4 |
| Miscellaneous | Defects in LZTS1 are found in many types of tumors. |
| Sequence similarities | Belongs to the LZTS family. |

| Isoform 1 (identifier: Q9Y250-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: Q9Y250-2) The sequence of this isoform differs from the canonical sequence as follows: 505-527: Missing. | ||||||
| Isoform 3 (identifier: Q9Y250-3) The sequence of this isoform differs from the canonical sequence as follows: 471-503: Missing. | ||||||
| Isoform 4 (identifier: Q9Y250-4) The sequence of this isoform differs from the canonical sequence as follows: 468-526: Missing. | ||||||
| Isoform 5 (identifier: Q9Y250-5) The sequence of this isoform differs from the canonical sequence as follows: 454-545: Missing. | ||||||
| Isoform 6 (identifier: Q9Y250-6) The sequence of this isoform differs from the canonical sequence as follows: 186-571: Missing. | ||||||
| Isoform 7 (identifier: Q9Y250-7) The sequence of this isoform differs from the canonical sequence as follows: 55-76: SSSKMGKSEDFFYIKVSQKARG → AMTRCPRASSMSGSCGRRRRRR 77-596: Missing. |
