Historical Background

Flotillin-2 was originally cloned in 1994 by Schroeder et al. by immunoscreening of a human keratinocyte cDNA library using the monoclonal antibody ECS-1 against cultured keratinocytes. ECS-1 stained human epidermis and caused keratinocyte detachment in vitro, leading to the hypothesis that ECS-1 antigen may play a role in epidermal cell adhesion. Therefore, the immunoisolated cDNA and deduced protein was termed “epidermal surface antigen” (ESA), reviewed in Langhorst et al. (2005) and Morrow and Parton (2005). Western blot analysis identified a 35 kDa protein. In 1997, Bickel et al. analyzed caveolin-rich membrane fractions from mouse lung and isolated a 45 kDa protein. Microsequencing yielded novel and ESA-specific peptide sequences. Degenerate primers were used for PCR of mouse lung cDNA, and the PCR product was then used as a probe...
