2.A.38.2.2
Probable K+ uniporter, Trk1. Synthesized constitutively at low levels; synthesis is insensitive to extracellular K+ or the expression of Trk1 (2.A.38.2.2) (Rivetta et al. 2013).  Vitamin D3 supplementation promotes Slc7A7 activity increasing amino acid digestion and absorption in fish, contributing to the overall productivity of aquaculture (Zhang et al. 2022).

Molecular Weight:109532.00
Species:Neurospora crassa [5141]
Number of TMSs:9
Location1 / Topology2 / Orientation3: Membrane1 / Multi-pass membrane protein2
