CRYSTAL STRUCTURE OF TWO CENTRAL SPECTRIN-LIKE REPEATS FROM ALPHA-ACTININ

The structure was published by Djinovic-Carugo, K., Young, P., Gautel, M., and Saraste, M., in 1999 in a paper entitled "Structure of the alpha-actinin rod: molecular basis for cross-linking of actin filaments." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 1999.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of HUMAN SKELETAL MUSCLE ALPHA-ACTININ 2. This molecule has the UniProt identifier P35609 (ACTN2_HUMAN)search. The sample contained 250 residues which is < 90% of the natural sequence. Out of 250 residues 248 were observed and are deposited in the PDB.

The molecule most likely forms homodimers.
