摘要 |
The present invention is directed to novel polypeptides, designated FIZZ, which are secreted low molecular weight molecules showing no significant sequence homology to any known protein, and nucleic acid sequences encoding such proteins. Also provided herein are vectors and host cells comprising those nucleic acid sequences, chimeric polypeptide molecules comprising the polypeptide of the present invention fused to heterologous polypeptide sequences, and antibodies which bind to the polypeptides of the present invention. Methods of using FIZZ polypeptides to treat various neurotrophin-related conditions are further provided. |
