The ADF (actin-depolymerizing factor)/cofilin family (see MIM 601442) is composed of stimulus-responsive mediators of actin dynamics. ADF/cofilin proteins are inactivated by kinases such as LIM domain kinase-1 (LIMK1; MIM 601329). The SSH family appears to play a role in actin dynamics by reactivating ADF/cofilin proteins in vivo (Niwa et al., 2002 [PubMed 11832213]).[supplied by OMIM

SSH1 (Slingshot protein phosphatase 1) is mainly involved in the actin filament organization. During cytokinesis, it reactivates ADF (actin-depolymerizing factor)/cofilin, which plays a major role in actin filament dynamics and cell migration. Apart from cofilin reactivation, it also dephosphorylates P-cofilin in vitro and in vivo. Overexpression of SSH1 has been reported in pancreatic cancer (PC) cells, which indicates its role in tumor cell migration via SSH1L/cofilin-1 signal pathway.

During cytokinesis the actomyosin-based contractile ring is formed at the equator, constricted, and then disassembled prior to cell abscission. Cofilin stimulates actin filament disassembly and is implicated in the regulation of contractile ring dynamics. However, little is known about the
The ADF (actin-depolymerizing factor)/cofilin family is a stimulus-responsive mediator of actin dynamics. In contrast to the mechanisms of inactivation of ADF/cofilin by kinases such as LIM-kinase 1 (LIMK1), much less is known about its reactivation through dephosphorylation. Here we report
Slingshot-1L (SSH1L), a cofilin-phosphatase, plays a role in actin dynamics and cell migration by reactivating cofilin-1. However, the expression of SSH1L in malignant diseases is poorly understood. The overexpression of SSH1L in cancerous tissue compared to the matched surrounding non-cancerous
