Anti-TRPV6 Antibody Picoband® Fluoro647 Conjugated

TRPV6 (Transient Receptor Potential Cation Channel Subfamily V Member 6), also known as ECAC2, CAT1 or CATL, a membrane calcium channel which is responsible for the first step in calcium absorption in the intestine. TRPV6 is a member of the Transient receptor potential (TRP) family of membrane proteins. Using FISH, Peng et al. (2000) mapped the TRPV6 gene to chromosome 7q33-q34. Peng et al. (2000) determined that TRPV6 mediates calcium uptake independent of sodium, chloride, and hydrogen; however, calcium influx was higher at alkaline rather than acidic pH. Functional analysis by Peng et al. (2001) indicated that TRPV5 mediates greater calcium uptake than TRPV6. They concluded that TRPV5 and TRPV6 are calcium-selective channels and share a common ancestral gene.

Involved in the homologous recombination repair (HRR) pathway of double-stranded DNA, thought to repair chromosomal fragmentation, translocations and deletions. Part of the Rad21 paralog protein complex BCDX2 which acts in the BRCA1-BRCA2-dependent HR pathway. Upon DNA damage, BCDX2 acts downstream of BRCA2 recruitment and upstream of RAD51 recruitment. BCDX2 binds predominantly to the intersection of the four duplex arms of the Holliday junction and to junction of replication forks. The BCDX2 complex was originally reported to bind single-stranded DNA, single-stranded gaps in duplex DNA and specifically to nicks in duplex DNA.
