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.

|---|---|
| Synonyms | IRK3 |
| Function | Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium; as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium. Can be blocked by extracellular barium and cesium (By similarity). |
| Cellular Location | Cell membrane; Multi-pass membrane protein. Postsynaptic cell membrane; Multi-pass membrane protein. Cytoplasmic vesicle membrane. Note=TAX1BP3 binding promotes dissociation of KCNJ4 from LIN7 famaly members and KCNJ4 internalization. |
| Tissue Location | Heart, skeletal muscle, and several different brain regions including the hippocampus |

Background
Several different potassium channels are known to beinvolved with electrical signaling in the nervous system. One classis activated by depolarization whereas a second class is not. Thelatter are referred to as inwardly rectifying K+ channels, and theyhave a greater tendency to allow potassium to flow into the cellrather than out of it. This asymmetry in potassium ion conductanceplays a key role in the excitability of muscle cells and neurons.The protein encoded by this gene is an integral membrane proteinand member of the inward rectifier potassium channel family. Theencoded protein has a small unitary conductance compared to othermembers of this protein family. Two transcript variants encodingthe same protein have been found for this gene.
