The importance of the Tec kinases in antigen receptor signaling was first demonstrated by the observation that mutations in BTK result in the human disease X-linked agammaglobulinemia (XLA) and the murine counterpart X-linked immunodeficiency ( xid ). These severe B cell immunodeficiencies are characterized by diminished numbers of mature B cells and reduced immunoglobulin levels associated with impaired PLC-γ activation and Ca ++mobilization in response to surface IgM stimulation (sIgM) [ 8, 9, 10, 11].
Btk kinase activity and tyrosine phosphorylation increase upon stimulation of sIgM as well as the IL-5 and IL6 receptors in B cells, and upon crosslinking of the high affinity IgE receptor (FcεRII) in mast cells [ 12, 13, 14, 15].
These results suggest that Rlk can be phosphorylated on Y420 in response to TCR stimulation, supporting a role for Rlk downstream of Src kinases in signaling from the TCR, analogous to Btk's role in signaling from sIgM.

Src kinases are activated within seconds of sIgM stimulation in B cells, while Btk is activated within minutes [ 14].
