Protein attributes
| Sequence length | 1023 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 | This is the catalytic component of the active enzyme, which catalyzes the hydrolysis of ATP coupled with the exchange of sodium and potassium ions across the plasma membrane. This action creates the electrochemical gradient of sodium and potassium ions, providing the energy for active transport of various nutrients. |
| Catalytic activity | ATP + H2O + Na+(In) + K+(Out) = ADP + phosphate + Na+(Out) + K+(In). |
| Subunit structure | Composed of three subunits: alpha (catalytic), beta and gamma. Binds the HLA class II histocompatibility antigen, DR1. |
| Subcellular location | Membrane; Multi-pass membrane protein. Melanosome. Note: Identified by mass spectrometry in melanosome fractions from stage I to stage IV. Ref.14 |
| Post-translational modification | Phosphorylation on Tyr-10 modulates pumping activity By similarity. |
| Sequence similarities | Belongs to the cation transport ATPase (P-type) family. Type IIC subfamily. |
Ontologies
Alternative products
| This entry describes 2 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform Long (identifier: P05023-1) 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 Short (identifier: P05023-2) The sequence of this isoform differs from the canonical sequence as follows: 638-681: NETVEDIAAR...DMTSEQLDDI → SGPMSRGKSW...PGGIRSSSRG 682-1023: Missing. | ||||||
| Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. |
