Protein attributes

Sequence length	131 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Binds to actin and affects the structure of the cytoskeleton. At high concentrations, profilin prevents the polymerization of actin, whereas it enhances it at low concentrations. By binding to PIP2, it inhibits the formation of IP3 and DG By similarity.
Subunit structure	Occurs in many kinds of cells as a complex with monomeric actin in a 1:1 ratio.
Subcellular location	Cytoplasm › cytoskeleton By similarity.
Allergenic properties	Causes an allergic reaction in human.
Sequence similarities	Belongs to the profilin family.
