General annotation (Comments)

Function

Transferrins are iron binding transport proteins which can bind two Fe3+ ions in association with the binding of an anion, usually bicarbonate. It is responsible for the transport of iron from sites of absorption and heme degradation to those of storage and utilization. Serum transferrin may also have a further role in stimulating cell proliferation.

Subunit structure

Monomer.

Subcellular location

Secreted.

Tissue specificity

Expressed by the liver and secreted in plasma.

Sequence similarities

Belongs to the transferrin family.

Contains 2 transferrin-like domains.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: P12346-1)

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.
Isoform 2 (identifier: P12346-2)

The sequence of this isoform differs from the canonical sequence as follows:
     65-266: Missing.
