Experimental Data

Contains experimentally-derived protein half-life data obtained using stable isotope labeling by amino acids (SILAC) coupled with mass spectrometry. This section also contains protein abundance data for both untreated and treated cells obtained from over 20 studies. These data have been normalized and converted to a common unit of molecules per cell.


Protein Half Life

No half-life data available for HTA2.

Domain Locations

Visual representation of the locations of the domains within the protein, as listed in the Domains and Classification table. Each row displays the domain(s) derived from a different Source, with domains color-coded according to this Source.

Scroll over a domain to view its exact coordinates and its Description.

Shared Domains

This diagram displays domains (colored squares) shared between the given protein (yellow circle) and other proteins (gray circles); the domains are color-coded according to their source, as displayed in the Domain Locations table, above.

Reset
