Title: ALKALs are in vivo ligands for ALK family receptor tyrosine kinases in the neural crest and derived cells.
In conclusion, these data show that ALK is robustly activated by the FAM150A/B ligands.
Title: FAM150A and FAM150B are activating ligands for anaplastic lymphoma kinase.
Data show FAM150B, which was named as augmentor-alpha (AUG-alpha), binds and activtes both anaplastic lymphoma kinase (ALK) and tyrosine kinase (LTK).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
