Rabbit anti-Human TIAM1 Polyclonal Antibody

Uniprot Id

Q13009

Target Species

Human

Target Name

TIAM1

Target Full Name

Rho guanine nucleotide exchange factor TIAM1

Target Function

Guanyl-nucleotide exchange factor that activates RHO-like proteins and connects extracellular signals to cytoskeletal activities. Activates RAC1, CDC42, and to a lesser extent RHOA and their downstream signaling to regulate processes like cell adhesion and cell migration.

Target Subcellular Location

Cell junction. Cell membrane; Peripheral membrane protein; Cytoplasmic side.

Target Protein Families

TIAM family

Target Tissue Specificity

Found in virtually all analyzed tumor cell lines including B- and T-lymphomas, neuroblastomas, melanomas and carcinomas.

Target Synonyms

Human T-lymphoma invasion and metastasis inducing TIAM1 protein; T cell lymphoma invasion and metastasis 1; T lymphoma invasion and metastasis inducing TIAM1 protein; T-lymphoma invasion and metastasis-inducing protein 1; TIAM-1; TIAM1; TIAM1_HUMAN

Target Background

This gene encodes a RAC1-specific guanine nucleotide exchange factor (GEF). GEFs mediate the exchange of guanosine diphosphate (GDP) for guanosine triphosphate (GTP). The binding of GTP induces a conformational change in RAC1 that allows downstream effectors to bind and transduce a signal. This gene thus regulates RAC1 signaling pathways that affect cell shape, migration, adhesion, growth, survival, and polarity, as well as influencing actin cytoskeletal formation, endocytosis, and membrane trafficking. This gene thus plays an important role in cell invasion, metastasis, and carcinogenesis. In addition to RAC1, the encoded protein activates additional Rho-like GTPases such as CDC42, RAC2, RAC3 and RHOA. This gene encodes multiple protein isoforms that experience a diverse array of intramolecular, protein-protein, and phosphorylation interactions as well as phosphoinositide binding. Both the longer and shorter isoforms have C-terminal Dbl homology (DH) and pleckstrin homology (PH) domains while only the longer isoforms of this gene have the N-terminal myristoylation site and the downstream N-terminal PH domain, ras-binding domain (RBD), and PSD-95/DlgA/ZO-1 (PDZ) domain.
