The name of this gene (XB-GENEPAGE-5734493, NCBI GeneID:100379934, XP_002932289.1) was changed from rasef , ras and EF-hand domain-containing protein to LOC100379934 , 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).
LOC100379934/rasef-like is very similar protein-wise to the true rasef, according to alignment in COBALT, and is flanked by different genes of course
in Gallus gallus (chicken) , the gene ( gene ID: 100858360 ) was already called 'ras and EF-hand domain-containing protein-like'.. and it has been indexed as an ortholog here.
Note that based on synteny (the conserved gene block), XB-GENE-1002558, NCBI GeneID: 780339, NP_001072877.1 represents the true ortholog to human RASEF (GeneID:158158), and accordingly it's name was changed from mgc147600 to rasef.
We have asked the HGNC to look at this gene to decide if it shoudl be called rasef-like or possible rasef2, a 2nd 'rasef' gene. Until then we will just keep the gene symbol as LOC100379934.
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 annotations, for X. tropicalis and X. laevis, Xenopus 'rasef-like' is on Chr3. Note that X. laevis has lost "serinc4. L and .S".
X. trop: serf2 ... rasef-like ... adamtsl5 ... serinc4 ... hypk
X. laevis.L: serf2.L ... rasef-like.L ... adamtsl5.L ... hypk.L
X. laevis.S LOC# ... rasef-like.S... adamtsl5.S ... hypk.S (reversed order)
Human: SERF2 .. SERF2-C15orf63 ... SERINC4 ...HYPK
Gallus: : SERF2 ... LOC100858360 ... SERINC4 ...HYPK
