Tech Info & Data

Background

 

The cDNA for Rheus/Cynomolgus IFN-Alpha 2 was cloned from the Rhesus cell line LLC-MK2. This was found to be identical to the putative Rhesus IFN-Alpha 2 (XM_001107516) identified as part of the Rhesus genome project. There are 14 AA differences in the mature protein (2 in the signal peptide) between the Rhesus and Human Alpha A (2a) sequence. There are 13 AA differences in the mature protein (2 in the signal peptide) between the Rhesus and Human Alpha 2 (2b) sequence. This is in accord with a previous report [Villinger et al. (1995) J. Immunol. 155:3946] stating that there are 15-16 amino acids different between the Rhesus IFN-Alpha 2 and human alpha 2 (2b) and human alpha A(2a) respectively.

 

This Rhesus (Macaca mulatta) sequence is also identical to a Cynomolgus (Macaca fascicularis) IFN-Alpha 2 cloned from cDNA isolated from primary hepatocytes (PBL unpublished observation).
