- lithium:proton antiporter activity
Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: Li+(in) + H+(out) = Li+(out) + H+(in).
- collagen type X trimer
A collagen homotrimer of alpha1(X) chains; type X collagen triple helices form hexagonal networks (sheets).
- ISG15 transferase activity
Catalysis of the transfer of ISG15 from one protein to another via the reaction X-ISG15 + Y = Y-ISG15 + X, where both X-ISG15 and Y-ISG15 are covalent linkages.
- FAT10 transferase activity
Catalysis of the transfer of FAT10 from one protein to another via the reaction X-FAT10 + Y = Y-FAT10 + X, where both X-FAT10 and Y-FAT10 are covalent linkages.
