Involved in cell polarization processes and the formation of epithelial tight junctions (By similarity). Catalytic activity: ATP + a protein = ADP + a phosphoprotein. Enzyme regulation: Might be a target for novel lipid activators that are elevated during nutrient-stimulated insulin secretion (By similarity). Fig. 1.

The alignment was downloaded from the HSSP database, and fragments shorter than 75% of the query as well as duplicate sequences were removed. It can be found in the attachment to this report, under the name of 1wmhA.msf. Its statistics, from the alistat program are the following: Format: MSF Number of sequences: 31 Total number of residues: 2540 Smallest: 73 Largest: 83 Average length: 81.9 Alignment length: 83 Average identity: 50% Most related pair: 99% Fig. 2. Residues in 1wmhA, colored by their relative importance. Clockwise: Most unrelated pair: 13% front, back, top and bottom views. Most distant seq: 33% Furthermore, 3% of residues show as conserved in this alignment. 2.4.1 Clustering of residues at 25% coverage. Fig. 3 shows the The alignment consists of 41% eukaryotic ( 25% vertebrata, 6% top 25% of all residues, this time colored according to clusters they arthropoda) sequences. (Descriptions of some sequences were not belong to. The clusters in Fig.3 are composed of the residues listed readily available.) The file containing the sequence descriptions can in Table 1. be found in the attachment, under the name 1wmhA.descr.
