General annotation (Comments)

Function

Carrier protein involved in proton-driven auxin influx. Mediates the formation of auxin gradient from developing leaves (site of auxin biosynthesis) to tips by contributing to the loading of auxin in vascular tissues and facilitating acropetal (base to tip) auxin transport within inner tissues of the root apex, and basipetal (tip to base) auxin transport within outer tissues of the root apex By similarity.

Subcellular location

Cell membrane; Multi-pass membrane protein By similarity.

Sequence similarities

Belongs to the amino acid/polyamine transporter 2 family. Amino acid/auxin permease (AAAP) (TC 2.A.18.1) subfamily. [View classification]

Alternative products

This entry describes 1 isoform produced by alternative splicing. [Select]

Note: A number of isoforms are produced. According to EST sequences.
Isoform 1 (identifier: Q9LFB2-1)

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.
