tensin4 TNS4) was defined as a faraway person in the tensin focal adhesion family members (Lo and Lo 2002 It really is a much smaller sized proteins compared to various other tensins in support of stocks the SH2 (Src homology 2) and PTB (phosphotyrosine binding) domains bought at the C-terminal ends of most various other tensins (Lo 2004 (body 1).
