The name of this gene (XB-GENEPAGE-5734493, NCBI GeneID:100379934, XP_002932289.1) was changed from rasef to rasef-like ras and EF-hand domain-containing protein-like, as represents a rasef-like gene that was lost in the ancestor of mammals. The orthologs have been removed from this Xenbase gene page ( and placed on the true rasef gene page).

rasef-like is very similar protein-wise to the true rasef, according to alignment in COBALT, and is flanked by different genes of course, and in Gallus gallus (chicken) , the LOC is also called 'ras and EF-hand domain-containing protein-like'.

XB-GENE-1002558, NCBI GeneID: 780339, NP_001072877.1 represents the true ortholog to human RASEF (GeneID:158158), and it's name was changed from mgc147600 to rasef.

Synteny pattern

For this rasef-like gene, the synteny data in Latimeria chalumnae and non-mammalian tetrapods is generally:

PDIA3>...ELL3<...FKBP8-like>...SERF2>...RASEF-like<...ADAMTSL5-like>...SERINC4<...HYPK>.

In chondrichthyes and teleosts this synteny is somewhat conserved but the gene block is often shorter or re-arranged. The neighboring FKBP8-like and ADAMTSL5-like genes are also often lost (or possibly unannotated) in reptiles and mammals.

According to the v10 genome annoations, for X. tropicalis and X. laevis, Xenopus 'rasef-like' is on Chr3.

Note that X. laevis has lost "serinc4".
