• impairment in the early and late phases of Ca2+ mobilization following BCR stimulation
• fail to proliferate after BCR cross linking
• following cross linking the frequency of cycling cells is reduced and the percentage of cells with greater than 2N DNA is increased

• less sensitive to anti-IgM induced proliferation compared to wild-type controls
• the percentage of peritoneal B220+CD5+ cells is decreased compared to wild-type controls but increased compared to mutant mice not carrying the transgene
• however, the frequency and number of splenic B cells are similar to wild-type controls
