Oligopeptide transporter 3

Gene

OPT3

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at transcript leveli

Functioni

May be involved in the translocation of tetra- and pentapeptides across the cellular membrane in an energy-dependent manner. Acts also as a metal transporter that could be a component of the copper transport machinery. Essential for early embryo development.3 Publications

Expressioni

Tissue specificityi

Strong expression in flowers, leaves and roots. Preferentially expressed in the vascular tissues of seedlings and mature plants as well as in pollen and developing embryos.2 Publications

Developmental stagei

Expressed 2 to 4 hours after fertilization in the embryo sac and subsequently in developing maternal tissues. By the globular stage, expression is observed in the developing endosperm, integument layers, the embryo proper, and the suspensor of the developing embryo. From the heart stage onward, expression observed in the embryo but neither in the suspensor nor in the endosperm and integument tissues.1 Publication

Inductioni

Highly induced by iron, copper and manganese deficiencies.1 Publication

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
