Function

Transfers sialic acid from CMP-sialic acid to galactose-containing acceptor substrates. In B lymphocytes, generates neuraminidase-sensitive lymphocyte cell-surface differentiation antigens, such as CDw75, HB-6 and CD76. Sialylates complex-type N-glycans attached on the fragment crystallizable (Fc) of IgGs confering anti-inflammatory effector functions.

Biological Context

Subcellular Location: Golgi apparatus, Golgi stack membrane (Single-pass type II membrane protein); Secreted
Pathway: Protein modification; protein glycosylation

Product Specifications

Recombinant Human Beta-galactoside alpha-2,6-sialyltransferase 1 (ST6GAL1) Protein is a recombinant protein from Homo sapiens (Human), expressed in in vitro E.coli expression system, covering amino acids 1-406aa, with N-terminal 6xHis-tagged tag, molecular weight 52.1kDa, purity Greater than 85% as determined by SDS-PAGE.. Suitable for ELISA and Western Blot applications.

SDS-PAGE: Single band at expected molecular weight confirming purity.

ELISA: Suitable as coating antigen or detection standard.

Function

Transfers sialic acid from CMP-sialic acid to galactose-containing acceptor substrates. In B lymphocytes, generates neuraminidase-sensitive lymphocyte cell-surface differentiation antigens, such as CDw75, HB-6 and CD76 (PubMed:1730763). Sialylates complex-type N-glycans attached on the fragment crystallizable (Fc) of IgGs confering anti-inflammatory effector functions. Preferentially monosialylates the alpha(1->3) mannose antenna of Fc glycoforms with subsequent disialylation occurring at a much slower rate
