Summary: Predicted to enable identical protein binding activity. Acts upstream of or within several processes, including cellular response to type II interferon; epithelial cell development; and skeletal muscle tissue development. Located in several cellular components, including brush border; focal adhesion; and stress fiber. Is expressed in several structures, including alimentary system; brain; facial prominence; limb mesenchyme; and skeleton. Used to study spondylocarpotarsal synostosis syndrome.

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: VALIDATED

Description

Transcript Variant: This variant (1) represents the longer transcript and encodes the longer isoform (a). This gene lacks full-length transcript support, and therefore the exon combination of this variant is inferred based on tiled partial transcripts and full-length orthologous alignments, e.g., human AF043045.1.

Description

Transcript Variant: This variant (2) uses an alternate in-frame splice site in the central coding region, compared to variant 1, resulting in an isoform (b) that is shorter than isoform a. This gene lacks full-length transcript support, and therefore the exon combination of this variant is inferred based on tiled partial transcripts and full-length orthologous alignments, e.g., human AB191258.1.
