Names and origin

Protein namesRecommended name:
T-cell receptor alpha chain C region
Gene names
Name:TRAC
Synonyms:TCRA
OrganismHomo sapiens (Human) [Reference proteome]
Taxonomic identifier9606 [NCBI]
Taxonomic lineageEukaryotaMetazoaChordataCraniataVertebrataEuteleostomiMammaliaEutheriaEuarchontogliresPrimatesHaplorrhiniCatarrhiniHominidaeHomo

Protein attributes

Sequence length142 AA.
Sequence statusComplete.
Protein existenceEvidence at protein level

General annotation (Comments)

Subcellular location

Membrane; Single-pass membrane protein Potential.

Miscellaneous

This clone was isolated from a human leukemic T-cell line, Jurkat.

This alpha chain C region shows sequence homology to its beta chain counterpart.

The gene corresponding to this mRNA is rearranged specifically in T-cells; its organization is similar to an Ig gene, with V, D, J, and C regions.

Sequence caution

The sequence CAA26435.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
