The members of the L1-family in humans are called L1 or L1cam, CHL1 (close homologue of L1), Neurofascin and NrCAM (NgCAM related cell adhesion molecule).
There are two homologue genes found in mammals, called Musashi 1 (MSI1) and Musashi 2 (Msi2).
Others such as Siglec-5 and Siglec-9 have homologues in mice and rats (Siglec-F and Siglec-E respectively in both).
