Auxin-binding protein (IPR000526)

Short name: Auxin-bd

Overlapping homologous superfamilies

Family relationships



Auxin binding protein is located in the lumen of the endoplasmic reticulum (ER). The primary structure contains an N-terminal hydrophobic leader sequence of 30-40 amino acids, which could represent a signal for translocation of the protein to the ER [PMID: 2555179, PMID: 1321684]. The mature protein comprises around 165 residues, and contains a number of potential N-glycosylation sites. In vitro transport studies have demonstrated co-translational glycosylation [PMID: 1321684]. Retention within the lumen of the ER correlates with an additional signal located at the C terminus, represented by the sequence Lys-Asp-Glu-Leu, known to be responsible for preventing secretion of proteins from the lumen of the ER in eukaryotic cells [PMID: 2555179, PMID: 1321684].
