nomenclature changes

13SEPT2023 Note there is currently a BUG in the curation interface preventing us from updating the summary section gene names and symbols- this will be fixed soon! the gene names have been changed from adam33 to adam13. Once these changes have cascaded through the database, target for MOs, Abs and gRNAs will be accurate. Until then, please use caution when re-using these reagent names, or interpreting target specificity.

13SEPT2023 The Xenopus name for this gene is changing from adam33 to adam13, following review by Xenbase staff and NCBI ref Seq team.

GeneID: 677728 (XB-GENE-988107) should be named ADAM13 rather than ADAM33 along with X. laevis L & S Gene ID: 386623 & Gene ID: 373720.

By synteny, the true Xtropicalis ortholog of human ADAM33 is GeneID: 101732075 (XB-GENE-29085839) along with X. laevis L & S GeneID: 108697349 & GeneID: 108704093.

The nomenclature error occurred because NCBI had a setting that prohibited the ADAM33 symbol from being applied to GeneID: 101732075. These true adam33 genes are represented on XB-GENEPAGE-29085838.

It appears that ADAM13 was lost in amniotes. The ADAM13 gene region in lower gnathostomes is quite variable so it's difficult to determine synteny outside of amphibia but we suspect the gene is present in most teleosts and sarcopterygian fish.

background to resolving adam13 v adam33 names

The protein ADAM13 (Alfandari et al., 1997 [1] is related to human ADAM33 but the sequences have diverged sufficiently that the two proteins cannot functionally replace each other.

Orthology (and thus accurate nomenclature) is being assessed by Xenbase and NCBI's ref seq and the HGNC.

ADAM13 is a cell surface metalloprotease that binds to its substrate via its cystein rich domain ([Gaultier et al., 2002][2]; [Smith et al., 2002][3]). ADAM13 binds and cleave fibronectin (Alfandari et al., 2001[4]), Cadherin-11 (McCusker et al., 2009[5]), PAPC (Cousin et al., 2011[6]) and ephrinB (Wei et al., 2011[7]).

ADAM13 also cleaves itself within its cystein rich domain (Gaultier et al., 2002[8]). This cleavage can be followed by a cleavage by gama-secretase that release the cytoplasmic domain. The ADAM13 cytoplasmic domain translocates into the nucleus where it regulates gene expression to promote cranial neural crest cell migration (Cousin et al., 2011[9]).

The cytoplasmic domain of ADAM13 interacts with multiple SH# containing proteins including PACSIN-2 which negatively regulates its proteolytic activity (Cousin et al., 2000 [10]).
