TWITCHIN KINASE FRAGMENT (C.ELEGANS), AUTOREGULATED PROTEIN KINASE AND IMMUNOGLOBULIN DOMAINS

The structure was published by Kobe, B., Heierhorst, J., Feil, S.C., et al., Benian, G.M., Weiss, K.R., and Kemp, B.E., in 1996 in a paper entitled "Giant protein kinases: domain interactions and structural basis of autoregulation." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.3 Å and deposited in 1996.

The experimental data on which the structure is based was also deposited.

The PDB entry contains the structure of TWITCHIN. This molecule has the UniProt identifier Q23551 (UNC22_CAEEL)search. The sample contained 491 residues which is < 90% of the natural sequence. Out of 491 residues 447 were observed and are deposited in the PDB.

The molecule most likely forms homodimers.
