PPAK
PFAM accession number:PF02818
Interpro abstract (IPR004168):

PPAK is a repeated protein motif found in the PEVK (Pro-Glu-Val-Lys) domain of the titin protein and in a number of other proteins. Titin (EC 2.7.11.1) is a giant elastic protein found in striated muscle that is a key component in the assembly and functioning of sarcomeres [(PUBMED:15507486)]. PPAK motifs (PPAK refers to the four amino acids found at the beginning of the motif) occur 60 times in human soleus titin [(PUBMED:11276084)]. PPAK motifs occur in groups of 2-12 that are separated by regions rich in glutamic acid (approximately 45%) and termed polyE segments. The charge fluctuation between the PPAK and polyE regions suggests ionic interactions between these segments and their involvement in the elastic function of titin.
