Background: Testican 3/SPOCK3

Testican 3 encoded by the SPOCK3 gene is a proteoglycan expressed in brain (1). Human and mouse Testican 3 share 90% amino acid sequence identity, indicating a conserved function (2, 3). Testican 3 contains Ca²⁺-binding domain and the C-terminal acidic domain with putative glycosaminoglycan attachment sites. In addition, it contains three potential inhibitory domains targeted toward three different classes of proteases, metallo, cysteine and serine proteases. The N-terminal region, which is unique to Testicans, is responsible for the inhibition of Testican 3 towards MMP-14/MT1-MMP activation of MMP-2 (1). The thyropin domain and the follistatin-like domain with a six cysteine Kazal-like motif may inhibit cysteine and serine proteases, respectively (4). A spliced variant designated as N-Tes contains the N-terminal unique region, the follistatin-like domain and the Ca²⁺-binding domain, but lacks the C-terminal thyropin domain and the acidic domain (1).
