B3: acta2-RCaMP1.07 Strain Information Sheet
Common Name: acta2-RCaMP1.07
CHROMusTM designation and lines available: R24:B3:L2; R24:B3:L3
Jackson Stock number: NA
Development: The red fluorescent calcium indicator RCaMP1.07 (a gift from Dr. Masamichi Ohkura, Brain Science Institute, Saitama University) was inserted at the ATG site of the acta2 gene in the BAC RP23-370F21 (CHORI) through homologous recombination. The resulting recombinant BAC was injected into the male pronucleus of fertilized oocytes which were then implanted into pseudo pregnant females. Resulting offspring were screened for the presence of the transgene (founders). Colonies were established from each founder and tested for expression.

Description: The genetically encoded calcium indicator RCaMP1.07 is expressed in smooth muscle cells in blood vessels, airways of the lung and gut. Expression may be present in other smooth muscle containing tissues which have not been examined. RCaMP1.07 responds to calcium levels in the cell. When calcium increases, a conformation change occurs resulting in an increase in fluorescence. When calcium decreases, fluorescence decreases. This mouse is useful for examining calcium signaling in smooth muscle tissues.
