ID IBP_CARCR Reviewed; 110 AA. AC P00993; DT 21-JUL-1986, integrated into UniProtKB/Swiss-Prot. DT 21-JUL-1986, sequence version 1. DT 15-FEB-2017, entry version 82. DE RecName: Full=Chelonianin; DE AltName: Full=Basic protease inhibitor; DE AltName: Full=RTPI; OS Caretta caretta (Loggerhead sea turtle). OC Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; OC Archelosauria; Testudines; Cryptodira; Durocryptodira; Americhelydia; OC Chelonioidea; Cheloniidae; Caretta. OX NCBI_TaxID=8467; RN [1] RP PROTEIN SEQUENCE. RC TISSUE=Egg white; RA Kato I., Tominaga N.; RT "Trypsin-subtilisin inhibitor from red sea turtle eggwhite consists of RT two tandem domains -- one Kunitz -- one of a new family."; RL Fed. Proc. 38:832-832(1979). CC -!- FUNCTION: The first domain inhibits trypsin; the second one CC inhibitis subtilisin. CC -!- CAUTION: As the paper only indicates the species as "red sea CC turtle", the species indicated here is therefore an inference. CC {ECO:0000305}.
