TSPAN5 is a member of the transmembrane 4 superfamily (TM4SF), also known as the tetraspanin (Tspan) family. Tetraspanins are cell surface glycoproteins with 4 transmembrane (TM) domains, intracellular N- and C-termini and two extracellular domains: one short (termed the small extracellular domain or loop, SED/SEL or EC1) and one longer, typically 100 amino acid residues (the large extracellular domain/loop, LED/LEL or EC2). Although several other protein families have 4 TM domains, tetraspanins are defined by conserved features including 4 or more cysteine residues in the EC2 domain, with 2 in a highly conserved 'CCG' motif. There are 34 tetraspanins in mammals, 33 of which have been identified in humans. The function of specific tetraspanins remains largely unclear. Tetraspanins are often thought to act as scaffolding proteins, anchoring multiple proteins to one area of the cell membrane.  Tetraspanins may function in many cellular processes including differentiation, adhesion, and signal transduction.  They may also contribute to pathological conditions such as metastasis or viral infection.

Product Details

 

Gene Symbol: TSPAN5; NET4; NET-4; TM4SF9; TSPAN-5

 

NCBI Gene ID: 10098

 

Uniprot Entry: P62079

 

Construct Details: Full length human TSPAN5 gene is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter and with or without a selection marker, which can be used for both transient and stable expression in mammalian cells.  It can be co-transfected with the LentiPAK DNA mix (SKU# LP-001) into HEK293 cells to produce high titer lentiviral particles. Multiple choices of a stable antibiotic selection marker are available.

 

Vector Type: pLTC or pLTC-IRES-Marker (lentiviral expression vector containing a heterologous CMV promoter +/- a selection marker, see the vector map above)

 

Formulation: Supplied with 10 μg of endotoxin-free plasmid DNA at 200 ng/μl in sterile TE buffer (pH8.0)

 

Gene Insert Size: 807 (bp)

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
