GlycoErase™ SIGLEC5 Knockout HEK293 Cell Line (CAT#: GLJF-0825-JF888)

Description	GlycoErase™ SIGLEC5 knockout HEK293 cell line is a HEK293 model in which SIGLEC5 expression has been deleted. SIGLEC5 belongs to the CD33-related subset and suppresses the activation of monocytes, macrophages, and neutrophils, and is also associated with bacterial immune evasion. The knockout HEK293 line provides a practical system to explore innate immune regulation, host-pathogen interactions, and immune escape, and supports applications in viral vector studies, antibody design, and molecular biology.

Target	SIGLEC5
Full Name	Sialic Acid Binding Ig Like Lectin 5
Alternative Name	CD170, OBBP2, CD33L2, OB-BP2, SIGLEC-5, Sialic Acid Binding Ig Like Lectin
Location	19q13.41
Gene ID	8778
Summary	This gene encodes a member of the sialic acid-binding immunoglobulin-like lectin (Siglec) family, characterized by structural motifs in the immunoglobulin-like domains and sialic acid recognition sites in the first Ig V-set domain. The encoded protein is part of the CD33-related Siglec subgroup and inhibits the activation of monocytes, macrophages, and neutrophils. It also plays a role in immune evasion by Group B Streptococcus (GBS).
