General annotation (Comments)

Function

Low-affinity, high capacity permease involved in the transport of the cationic amino acids (arginine, lysine and ornithine). Plays a regulatory role in classical or alternative activation of macrophages By similarity.

Subcellular location

Membrane; Multi-pass membrane protein Potential.

Sequence similarities

Belongs to the amino acid-polyamine-organocation (APC) superfamily. Cationic amino acid transporter (CAT) (TC 2.A.3.3) family. [View classification]

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: B5D5N9-1)

Also known as: CAT2A;

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: B5D5N9-2)

Also known as: CAT2B;

The sequence of this isoform differs from the canonical sequence as follows:
     357-397: MFPLPRILFA...AATMTAGVIS → IFPMPRVIYA...IATLSSGAVA
