- 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).
- obsolete ALP binding
OBSOLETE. Interacting selectively and non-covalently with ALP, actinin-associated LIM protein of the Z band. ALP is a PDZ/LIM domain protein found in the Z band.
- FATZ binding
Binding to a member of the FATZ family of proteins, filamin-, actinin-, and telethonin-binding proteins of the Z-disc of striated muscle. FATZ proteins are located in the Z-disc of the sarcomere and are involved in a complex network of interactions with other Z-band components.
