An internal ribosome entry site element directs the synthesis of the 80 kDa isoforms of protein 4.1R.

Background: In red blood cells, protein 4.1 (4.1R) is an 80 kDa protein that stabilizes the spectrin-actin network and anchors it to the plasma membrane through its FERM domain.

Protein 4.1R self-association: identification of the binding domain.

Erythroid protein 4.1 (4.1R) stabilizes the spectrin-actin network and anchors it to the plasma membrane.

Protein 4.1R regulates interphase microtubule organization at the centrosome.

In human red blood cells, protein 4.1 (4.1R) stabilizes the spectrin-actin network and anchors it to the plasma membrane.

An alternative domain containing a leucine-rich sequence regulates nuclear cytoplasmic localization of protein 4.1R.

In red blood cells, protein 4.1 (4.1R) is an 80-kDa protein that stabilizes the spectrin-actin network and anchors it to the plasma membrane.
