This 24 amino acid peptide (Fukutomi et al., 2012) is unique in NCBI and there are no highly similar proteins identified by BLAST.

Osamu Ishibashi submitted in September, 2016. Numbe Lip b 1.0101 has a 100% match to the 24 mer identified by Fukutomi and accepted by IUIS in 2012. the full length sequence will be shown in 2017.

Posted: 28 Jan 2018

The peptide fragment of 24 AA is an exact match to the longer protein of Lip b 1.0101. Thus it can be ignored. The sequences of the two long proteins were released in Jan 2017. REG
