The interaction between I-band titin domains and sHSPs in GST pulldown assays. Representative Western blots demonstrating the presence or absence of an interaction of HSP27 (A) or αB-crystallin (B) with various I-band titin domains. (C) Overview of HSP27 and αB-crystallin interaction sites on I-band titin detected by this assay. Results marked by as asterisk were obtained previously (Bullard et al., 2004). The I9-12 Ig segment likely also binds αB-crystallin (Zhu et al., 2009). asPEVK, alternatively spliced PEVK.
