Large neutral amino acids transporter small subunit 2 (SLC7A8)

Sodium-independent, high-affinity transport of small and large neutral amino acids such as alanine, serine, threonine, cysteine, phenylalanine, tyrosine, leucine, arginine and tryptophan, when associated with SLC3A2/4F2hc. Has greater affinity for L-phenylalanine than LAT1 but lower affinity for glutamine and serine.

L-alanine is transported at physiological concentrations. Plays a role in basolateral (re)absorption of neutral amino acids.
