Foundational characteristics of cancer include proliferation, angiogenesis, migration, evasion of apoptosis, and cellular immortality. Find key markers for these cellular processes and antibodies to detect them.
The SUMOplot™ Analysis Program predicts and scores sumoylation sites in your protein. SUMOylation is a post-translational modification involved in various cellular processes, such as nuclear-cytosolic transport, transcriptional regulation, apoptosis, protein stability, response to stress, and progression through the cell cycle.
The Autophagy Receptor Motif Plotter predicts and scores autophagy receptor binding sites in your protein. Identifying proteins connected to this pathway is critical to understanding the role of autophagy in physiological as well as pathological processes such as development, differentiation, neurodegenerative diseases, stress, infection, and cancer.

- PROTOCOLS
- BACKGROUND
| Primary Accession | Q15262 |
|---|---|
| Clone Names | 1121008 |
| Gene ID | 5796 |
|---|---|
| Other Names | Receptor-type tyrosine-protein phosphatase kappa, Protein-tyrosine phosphatase kappa, R-PTP-kappa, PTPRK, PTPK |
| Target/Specificity | The synthetic peptide sequence used to generate the antibody AP8417a was selected from the N-term region of human PTPkappa . A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay. |

| Storage | Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C. |
| Precautions | This product is for research use only. Not for use in diagnostic or therapeutic procedures. |
| Name | PTPRK |
|---|---|
| Synonyms | PTPK |
| Function | Regulation of processes involving cell contact and adhesion such as growth control, tumor invasion, and metastasis. Negative regulator of EGFR signaling pathway. Forms complexes with beta-catenin and gamma-catenin/plakoglobin. Beta-catenin may be a substrate for the catalytic activity of PTPRK/PTP-kappa. |
| Cellular Location | Cell junction, adherens junction. Cell membrane; Single-pass type I membrane protein |
| Tissue Location | High levels in lung, brain and colon; less in liver, pancreas, stomach, kidney, placenta and mammary carcinoma |

Background
PTPkappa, a member of the receptor class 2B subfamily of protein-tyrosine phophatases, is involved in regulation of processes involving cell contact and adhesion such as growth control, tumor invasion, and metastasis. It forms complexes with beta-catenin and gamma-catenin/plakoglobin. Beta-catenin may be a substrate for the catalytic activity of PTP-kappa. This Type I membrane protein, localized at adherens junctions, is found at high levels in lung, brain and colon; less in liver, pancreas, stomach, kidney, placenta and mammary carcinoma. It contains 4 fibronectin type III domains, 1 immunoglobulin-like C2-type domain, 1 MAM domain, and 2 protein-tyrosine phosphatase domains.
