TEL (ETV6) protein products are nuclear phosphoproteins that display specific DNA-binding activity toward classical ETS binding sites; two isoforms of 50 kDa and 57 kDa are produced by translation initiation at either of the two first in-frame ATGs (codon 1 and 43), and both are modified by multiple phosphorylation events in vivo. |
