Ex Input:
 Siglec - 9 is predicted to contain three extracellular immunoglobulin - like domains that comprise an N - terminal V - set domain and two C2 - set domains , a transmembrane region and a cytoplasmic tail containing two putative tyrosine - based signaling motifs .

Ex Output:
Siglec - 9


Ex Input:
 Molecular analysis indicated that inactivation of H - 2L expression in nearly every null clone resulted from an apparent deletion or rearrangement of 5 ' - flanking and 5 ' - coding H - 2L sequences , with breakpoints consistently mapping to within a 550 bp GC - rich region between exon 1 and the middle of intron 2 .

Ex Output:
H - 2L


Ex Input:
