Summary: The protein encoded by this gene is a member of the fibroblast growth factor receptor (FGFR) family, where amino acid sequence is highly conserved between members and throughout evolution. FGFR family members differ from one another in their ligand affinities and tissue distribution. A full-length representative protein consists of an extracellular region, composed of three immunoglobulin-like domains, a single hydrophobic membrane-spanning segment and a cytoplasmic tyrosine kinase domain. The extracellular portion of the protein interacts with fibroblast growth factors, setting in motion a cascade of downstream signals, ultimately influencing mitogenesis and differentiation. This particular family member binds both acidic and basic fibroblast growth factors and is involved in limb induction. Mutations in this gene have been associated with Pfeiffer syndrome, Jackson-Weiss syndrome, Antley-Bixler syndrome, osteoglophonic dysplasia, and autosomal dominant Kallmann syndrome 2. Chromosomal aberrations involving this gene are associated with stem cell myeloproliferative disorder and stem cell leukemia lymphoma syndrome. Alternatively spliced variants which encode different protein isoforms have been described; however, not all variants have been fully characterized. [provided by RefSeq, Jul 2008]

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.

Status: REVIEWED

Description

Transcript Variant: This variant (2) uses an alternate in-frame splice site in the 5' coding region, compared to variant 1. The resulting isoform (2), also known as isoform A, III, and the 3-Ig domain form, lacks a 2-aa segment, compared to isoform 1. Both variants 2 and 12 encode the same isoform.

Status: REVIEWED

Description

Transcript Variant: This variant (4) lacks an alternate in-frame exon and uses a different in-frame splice junction compared to variant 1. This variant encodes isoform 4, also known as isoform I, H3, and the 2-Ig Domain form, which is 91 aa shorter than isoform 1.

Suppressed Reference Sequence(s)

The following Reference Sequences have been suppressed. Explain

NM_023107.2: Suppressed sequence

Description

NM_023107.2: This RefSeq was permanently suppressed because currently there is insufficient support for the transcript and the protein.
NM_023108.2: Suppressed sequence

Description

NM_023108.2: This RefSeq was permanently suppressed because currently there is insufficient support for the transcript and the protein.
NM_023109.1: Suppressed sequence

Description

NM_023109.1: This RefSeq was permanently suppressed because it is a nonsense-mediated mRNA decay (NMD) candidate.
NM_023111.2: Suppressed sequence

Description

NM_023111.2: This RefSeq was permanently suppressed because it represents a poorly supported variant with non-consensus splice sites.
NM_032191.1: Suppressed sequence

Description

NM_032191.1: This RefSeq was permanently suppressed because it contains the wrong CDS.
