Chromosomal assignment of the recoverin gene and cancer-associated retinopathy.
The deduced amino acid sequence of the recently cloned mouse 23kD photoreceptor cell-specific protein showed it to be identical to the recoverin protein and the CAR (cancer-associated retinopathy) protein. DNA sequence variants were found in the mouse recoverin gene (Rcvrn), and segregation analysis of restriction fragment length variants in recombinant inbred strains of mice assigned Rcvrn to mouse Chromosome (Chr) 11, between Sparc (3.7 map units) and Zfp-3 (2.3 map units). These results demonstrate a close linkage of recoverin to the tumor suppressor gene, Trp53. On the basis of these data, knowledge of the function of recoverin, and the characteristics of CAR, an experimentally testable model is presented to explain the molecular basis for CAR.
