Zasp/Cypher internal ZM-motif containing fragments are sufficient to co-localize with α-actinin—Analysis of patient mutations

2005

Z-band alternatively spliced PDZ-containing protein (ZASP/Cypher) has an important role in maintaining Z-disc stability in striated and cardiac muscle. ZASP/Cypher interacts through its PDZ domain with the major Z-disc actin cross-linker, alpha-actinin. ZASP/Cypher also has a conserved sequence called the ZM-motif, and it is found in two alternatively spliced exons 4 and 6. We have shown earlier that the ZM-motif containing internal regions of two related proteins ALP and CLP36 interact with alpha-actinin rod region, and that the ZM-motif is important in targeting ALP to the alpha-actinin containing structures in cell. Here, we show that the ZASP/Cypher internal fragments containing either …
